      Re:   Benjamin Franklin Bancorp, Inc.
            Form S-1, filed December 10, 2004
            File No. 333-121154

Ladies and Gentlemen:

"Registrant"), following this letter is a electronic filing of Amendment No. 1

      In addition, set forth below and attached hereto are the Registrant's

with exhibits thereto, are being delivered under separate cover to Mark Webb,
Barry McCarty, Donald Walker and Sharon Johnson for the convenience of the
Staff. The changes marked in the courtesy copies are number-keyed to the Staff's
comment letter. Page references in this letter refer to the printed (rather than
the EDGAR) version of Amendment No. 1 (the pagination is may be slightly

Statement on Form S-4 filed December 23, 2004 (File No. 333-121608) and

FORM S-1

GENERAL

1.    PLEASE USE THE SAME SIZE TYPE THROUGHOUT THE DOCUMENT, I.E. NOT A SMALLER
      TYPE FOR FOOTNOTES AND FINANCIAL INFORMATION.

      In response to this comment and further clarification from the staff, the
      Registration Statement has been modified so that all of the type in the
      prospectus is in 10 point type or larger.

COVER PAGE

2.    PLEASE CONFIRM THAT THE COVER PAGE WILL BE LIMITED TO ONE PAGE.

      The Registrant confirms that the cover page to the Registration Statement
      will be limited to one page.

3.    PLEASE PROVIDE US WITH YOUR LEGAL ANALYSIS SUPPORTING THE MINIMUM OFFERING
      STRUCTURE IN YOUR STATEMENT: "IF WE DO NOT RECEIVE ORDERS FOR AT LEAST
      THIS MINIMUM [4,250,000] NUMBER OF SHARES, THEN WE MAY APPLY UP TO
      2,082,500 UNSUBSCRIBED SHARES TOWARD THE MERGER CONSIDERATION TO BE PAID
      TO CHART BANK STOCKHOLDERS, BUT ONLY IN ORDER TO ISSUE SUFFICIENT SHARES
      TO ACHIEVE THIS MINIMUM NUMBER." WE MAY HAVE FURTHER COMMENT BASED UPON
      YOUR RESPONSE.

      This structure is solely for bank regulatory purposes. All the shares
      issued to the Chart Bank stockholders will be sold under the Registration
      Statement on Form S-4, and the shares issued to depositors and others in
      the conversion will be sold under the Registration Statement on Form S-1.
      However, banking regulations require that, in a mutual to stock
      conversion, the converting institution must sell its stock at a total
      price equal to the estimated pro forma market value of such stock based on
      an independent valuation. In order to meet this banking law requirement,
      the Registrant has asked the Massachusetts Commissioner of Banks for
      approval to "count" some of the shares issued to the Chart Bank
      stockholders under the Form S-4 as shares issued in the conversion, if
      orders for the minimum reflected in the independent appraisal are not
      received.

      Benjamin Franklin Bancorp has no reason to believe that it will not
      generate orders for the minimum number of shares through its subscription
      offering and community offering. However, the Board of Directors
      determined that it would be appropriate to build into the Plan of
      Conversion the flexibility to "count" some of the shares issued to the
      Chart Bank stockholders toward this minimum, in the event that market
      conditions at the time of the offering result in fewer orders than
      expected. The Board believes that utilizing this provision of its Plan of
      Conversion may, under certain circumstances, be preferable to undergoing
      the

Securities and Exchange Commission
January 24, 2005
Page 3


      expense of conducting a syndicated community offering, especially if only
      a small number of shares remain to be issued to reach the minimum.

      The Board believes that this provision of its Plan is appropriate in light
      of the fact that persons entitled to purchase shares in the conversion
      offering (depositors and others) would not be precluded from purchasing
      shares. If this provision of the Plan of Conversion is utilized, all
      persons with subscription rights--indeed, all persons who wish to purchase
      shares in the direct community offering--will have had the opportunity to
      purchase their full subscriptions. In addition, if this provision of the
      Plan were utilized, the exchange of Chart Bank's shares for stock of
      Benjamin Franklin Bancorp would basically be the same as a continuation of
      the public offering, except that Chart Bank's securities would be taken as
      consideration instead of cash.

      This approach has been followed in at least two other conversions--the
      conversion of Harris Financial, MHC of Harris, Pennsylvania (which changed
      its name to Waypoint Financial Corp.) and simultaneous acquisition of York
      Financial, Inc. in 2000, and the conversion of Provident Bancorp MHC and
      simultaneous acquisition of E.N.B Holding Company, Inc., in 2003. In each
      case, the Office of Thrift Supervision was the banking regulator involved
      in the transaction and concluded that the provision was appropriate for
      the reasons set forth in the preceding paragraph. This is the first
      conversion to propose the use of such a provision under Massachusetts law.
      At the request of the Massachusetts Commissioner of Banks, the prospectus
      has been modified to indicate that the use of this provision will be
      subject to regulatory approval.

4.    PLEASE KNOCK DOWN THE ALL CAPITAL LETTER LEGENDS. RATHER THAN ALL CAPITAL
      LETTERS, CONSIDER USING BOLD FACE TYPE AND/OR ITALICS.

      The cover page to the prospectus has been modified in response to this
      comment.

5.    PLEASE SEPARATE THE FDIC LEGEND FROM THE FINAL LEGEND.

      The cover page to the prospectus has been modified in response to this
      comment.

SUMMARY

6.    PLEASE ADD A NEW SUBSECTION ENTITLED "BENEFITS TO OFFICERS AND DIRECTORS
      IN CONJUNCTION WITH THE CONVERSION" DIRECTLY FOLLOWING THE AFTER-MARKET
      PERFORMANCE SECTION BEGINNING ON PAGE 6. WE NOTE THE STOCK-BASED BENEFITS
      DISCLOSURE BEGINNING ON PAGE 12. PLEASE INTEGRATE THIS DISCLOSURE WITH THE
      NEW SUBSECTION REFERENCED IN THE FIRST SENTENCE.

      The Registration Statement has been modified in response to this comment.
      See Amendment No. 1, page 7.

7.    IN ADDITION, PLEASE ADD DISCLOSURE REGARDING THE VALUE OF THE FREE STOCK
      ($8-$14) CONSISTENT WITH RECENT THRIFT CONVERSIONS.

      The Registration Statement has been modified in response to this comment.
      See Amendment No. 1, page 9.


CHARITABLE FOUNDATION- PAGE 10

8.    REGARDING THE DONATION OF 8% OF THE SHARES TO A CHARITY CONTROLLED BY BEN
      FRANKLIN, PLEASE CLARIFY BY COMPARING THE ESTIMATED VALUE RANGE OF THIS
      CHARITABLE DONATION WITH RECENT CHARITABLE DONATIONS BY BEN FRANKLIN, AND
      THE DILUTION, ON A PER SHARE BASIS, TO SHAREHOLDERS.

      The Registration Statement has been modified in response to this comment.
      See Amendment No. 1, page 14.


TAX CONSEQUENCES OF THE CONVERSION- PAGE 14

9.    PLEASE CLARIFY TO DISCLOSE COUNSEL'S TAX OPINION REGARDING THE FEDERAL
      INCOME TAX CONSEQUENCES TO DEPOSITORS AND OTHERS WHO RECEIVE SUBSCRIPTION
      RIGHTS IN THE CONVERSION.

      The Registration Statement has been modified in response to this comment.
      See Amendment No. 1, page 16.

10.   PLEASE DELETE THE PHRASE "TO THE EFFECT" FOUND IN THE THIRD LINE OF THIS
      SECTION.

      The Registration Statement has been modified in response to this comment.
      See Amendment No. 1, page 16.


      RELATIVELY HIGH PRO FORMA PRICING MULTIPLES MAY NEGATIVELY AFFECT AFTER
      MARKET STOCK PERFORMANCE COMPARED WITH OTHER RECENTLY CONVERTED
      INSTITUTIONS- PAGE 24

11.   PLEASE ADVISE REGARDING THE COMPARABLE TRANSACTIONS; FOR EXAMPLE,
      NEWALLIANCE IS A RECENT CONVERSION MERGER.

      The Registration Statement has been modified in response to this comment.
      See Amendment No. 1, page 26.

12.   PLEASE CLARIFY BY ADDING THE PEER GROUP TRADING MULTIPLES, WHICH ARE
      APPROXIMATELY 40% HIGHER THAN BEN FRANKLIN'S PRO FORMA TANGIBLE BOOK
      MULTIPLE.

      We believe that the peer group trading multiples, which are disclosed on
      page 5 of Amendment No. 1, would not serve to clarify this risk factor.
      The purpose of this risk factor is to compare pro forma pricing ratios of
      recent conversions, and

Securities and Exchange Commission
January 24, 2005
Page 5


      to caution investors (who may assume that all conversion offerings have
      similar pro forma pricing multiples) that the pro forma pricing ratios in
      this offering are significantly higher than those of other mutual-to-stock
      conversion offerings. The risk factor does not purport to compare the pro
      forma pricing ratios of Benjamin Franklin Bancorp with the actual pricing
      ratios of thrifts that are already publicly traded, and repeating such
      information in this risk factor could cause confusion.

13.   IN ADDITION, PLEASE ADVISE WHY THE BOOK VALUE MULTIPLE ISN'T INCLUDED TO
      PROVIDE CONTEXT.

      Because intangible assets are not included in regulatory capital and do
      not provide earnings power in the form of interest-earning assets,
      investors generally omit intangible assets when making investment
      decisions. For this reason, the prospectus places greater emphasis on
      measures of pro forma tangible stockholders' equity in assessing relative
      value than on pro forma stockholders' equity.

THE IMPLEMENTATION OF STOCK-BASED BENEFIT PLANS MAY DILUTE YOUR OWNERSHIP
INTEREST PAGE 24

14.   IT APPEARS THAT STOCK-BASED BENEFIT PLANS WILL DILUTE SHAREHOLDER
      OWNERSHIP INTEREST. PLEASE REVISE ACCORDINGLY.

      It is the Registrant's intention to fund the stock-based incentive plan
      with open market purchases, so the original disclosure is accurate.
      However, in the heading to this risk factor we have changed the word "may"
      to "will" in recognition that the Registrant's current intention could
      change over the life of the plan. See Amendment No. 1, page 26.

CAPITALIZATION - PAGE 32

15.   PLEASE REVISE TO QUANTIFY THE PRO FORMA EFFECTS OF THE ACQUISITION OF
      CHART BANK IN A SEPARATE COLUMN. ALSO, REVISE TO PRESENT THE PRO FORMA
      EFFECTS OF THE ACQUISITION TO THE RIGHT OF THE PRO FORMA EFFECTS OF THE
      CONVERSION, SIMILAR TO THE PRO FORMA FINANCIAL STATEMENTS ON PAGE 36.

      In response to this comment and further clarification from the staff, the
      Registration Statement has been modified to include a new column showing
      the pro forma merger adjustments. See Amendment No. 1, page 35


PRO FORMA BALANCE SHEETS - PAGE 36

      CONSOLIDATED STATEMENTS OF FINANCIAL CONDITION SHOULD BE MADE TO CASH AND

      CASH EQUIVALENTS RATHER THAN SECURITIES AVAILABLE FOR SALE AT FAIR VALUE.

      See Amendment No. 1 pages 40, 43, 46 and 49.

17.   PLEASE REVISE THE FOOTNOTES HERE AND ON YOUR PRO FORMA STATEMENTS OF
      INCOME TO QUANTIFY THE COMPONENTS AND TOTALS OF PRO FORMA ADJUSTMENTS

COMMERCIAL REAL ESTATE LOANS - PAGE 64

18.   PLEASE ADD DISCLOSURE REGARDING THE AVERAGE YIELD FOR YOUR COMMERCIAL REAL
      ESTATE LOAN PORTFOLIO AT THE VARIOUS PERIODS YOU MENTION. IN ADDITION,
      EXPAND ON WHY YOU INTEND ON GROWING THIS PART OF YOUR LOAN PORTFOLIO AND
      ANY NEW UNDERWRITING CRITERIA DESIGNED TO LIMIT RISK.

      The Registration Statement has been modified in response to this comment.
      See Amendment No. 1, page 74. Please note that Benjamin Franklin Bank does
      not expect to modify its fundamental underwriting criteria, because
      management believes that its existing credit evaluation criteria and
      ongoing risk management systems will adequately protect the Bank.
      Management believes that the underwriting criteria described in detail in
      the "Business of Benjamin Franklin Bancorp"; the experience of the Bank's
      lending staff, senior management and the Board in commercial lending; the
      Bank's knowledge of the Benjamin Franklin and Chart Bank lending market
      areas; the quality of the Bank's loan review procedures; and the Bank's
      commitment to maintaining an adequate Allowance for Loan Losses will
      enable the Bank to accomplish this potential growth in a prudent manner.
      Management expects to remain alert to changes in the environment that
      could change the risk profile of the Bank's commercial lending activities,
      and will make adjustments to the Bank's underwriting criteria should
      circumstances so warrant.

      19. PROVIDE SIMILAR DISCLOSURE FOR CONSTRUCTION LOANS, HOME EQUITY,
      COMMERCIAL BUSINESS, AS WELL AS CONSUMER LOANS.

      The Registration Statement has been modified in response to this comment.
      See Amendment No. 1, pages 73-76.

      OTHER-THAN-TEMPORARY IMPAIRMENT LOSSES ON SECURITIES ARE PARTICULARLY
      SUBJECT TO CHANGE. PLEASE REVISE TO CLARIFY WHY THOSE ESTIMATES ARE NOT
      CONSIDERED CRITICAL, OR ADVISE.

      Given the nature of Benjamin Franklin's investment portfolios, page F-10
      has been revised to delete the categorization of other-than-temporary
      impairment losses on securities as a material estimate that is susceptible
      to significant change in the near term.

23.   YOU STATE THAT GOODWILL IS REGULARLY EVALUATED FOR IMPAIRMENT, WHICH
      INVOLVES TRACKING AND MEASURING THE FAIR VALUE OF THE BUSINESS UNIT
      ACQUIRED. ON PAGE F14, YOU STATE THAT YOU DO NOT TRACK THE SEPARATE VALUE
      OF FOXBORO NATIONAL BANK (TO WHICH ALL OF YOUR GOODWILL RELATES).

MANAGEMENT'S DISCUSSION AND ANALYSIS - LIQUIDITY RISK MANAGEMENT - PAGE 99

24.   WE NOTE THAT CASH PROVIDED BY OPERATIONS DECREASED FIFTY PERCENT FROM
      DECEMBER 30, 2003 TO SEPTEMBER 30, 2004. WE ALSO NOTE THAT CASH PROVIDED
      BY FINANCING ACTIVITIES INCREASED EIGHT HUNDRED PERCENT DURING THE SAME
      PERIOD. PLEASE REVISE TO PROVIDE A SIGNIFICANTLY ENHANCED DISCUSSION AND
      ANALYSIS OF YOUR LIQUIDITY AND CAPITAL POSITIONS. USE THE STATEMENT OF
      CASH FLOWS IN ANALYZING LIQUIDITY AND PRESENT A BALANCED DISCUSSION
      DEALING WITH CASH FLOWS FROM OPERATING, INVESTING AND FINANCING
      ACTIVITIES. SINCE THERE HAS BEEN MATERIAL VARIABILITY IN HISTORICAL CASH
      FLOWS, DISCUSS THE UNDERLYING REASONS FOR THE CHANGES, AS WELL AS THEIR
      REASONABLY LIKELY IMPACT ON FUTURE CASH FLOWS AND CASH MANAGEMENT
      DECISIONS. ALSO, DISCUSS PROSPECTIVE INFORMATION REGARDING SHORT AND LONG
      TERM SOURCES OF CAPITAL AND THE NEED FOR CAPITAL. SPECIFICALLY, DISCUSS
      HOW THE CONVERSION, OFFERING AND ACQUISITION OF CHART BANK WILL AFFECT
      YOUR FUTURE LIQUIDITY AND CAPITAL POSITIONS. REFER TO SECTION IV OF SEC
      FINANCIAL REPORTING RELEASE 72.

      The Consolidated Statements of Cash Flows on page F-7 have been revised to
      reclassify the Bank's purchase of bank-owned life insurance ("BOLI") from
      cash flows from operating activities to cash flows from investing
      activities. With this reclassification, the variance in net cash provided
      by operating activities in the 2004 and 2003 nine month periods is reduced
      to 24.5%. Further, as the cash flow statement now more clearly shows, this
      variance is caused primarily by changes in the other assets and
      liabilities, and in particular by fluctuation in the Bank's official
      checks liability account. In response to the request for additional
      discussion of the Bank's financing activities and capital resources, the
      Registration Statement has been revised. See Amendment No. 1, page 11.

      (ORIGINATION) PRINCIPAL PAYMENTS, NET. CLARIFY WHETHER THE AMOUNTS
      PURCHASED REPRESENT PURCHASES OF LOANS OR PURCHASES OF LOAN

      131 IN YOUR DETERMINATION NOT TO REPORT SEGMENT INFORMATION FOR BENJAMIN
      FRANKLIN BANK SECURITIES CORP.

      Benjamin Franklin Securities Corp. ("BFSC") does not meet the criteria
      outlined in paragraph 10 of SFAS 131, because while BFSC earns revenues
      and has discrete financial information available for it, its operating
      results are not regularly reviewed by Benjamin Franklin Bancorp's chief
      operating decision-maker. BFSC exists solely to buy, sell and hold
      investment securities, and was

      formed for this purpose because income earned on investment securities
      held by entities that are qualified as "securities corporations" under
      Massachusetts law are subject to a significantly lower rate of state
      income tax than that assessed on income earned on investment securities
      maintained at Benjamin Franklin Bank.

      CHARACTERISTICS OF THE UNDERLYING FINANCIAL ASSETS USED TO STRATIFY
      SERVICING ASSETS FOR PURPOSES OF MEASURING IMPAIRMENT. FOR EXAMPLE, YOU

NOTE 6- SERVICING -PAGE F-25

40.   SUPPLEMENTALLY TELL US HOW THE FAIR VALUES OF YOUR MORTGAGE SERVICING
      ASSETS WERE DETERMINED FOR EACH PERIOD PRESENTED. WE WOULD EXPECT THE FAIR
      VALUES TO BE LOWER THAN THE CARRYING VALUES IN A DECLINING INTEREST RATE
      ENVIRONMENT. CLARIFY WHETHER YOU HAVE A VALUATION ALLOWANCE FOR THESE
      ASSETS AND REVISE TO PROVIDE THE DISCLOSURES REQUIRED BY PARAGRAPH 17E (4)
      OF SFAS 140.

      The quarterly valuation of the mortgage servicing rights ("MSR") asset is
      determined by stratifying the servicing portfolio as of each quarter-end
      date. The stratification of the servicing portfolio is based off of the
      original maturity date of the mortgages, using a weighted average interest
      rate and maturity date within each stratum. The servicing value or price
      multiple for the various strata is obtained from national mortgage
      industry sources such as "Mortgage Servicing News'" web site. The MSR
      asset value is obtained by taking the price multiple times the servicing
      rate of 25 basis points. This product is then multiplied by the unpaid
      principal balance to arrive at a market value.

      The Bank does not have a valuation allowance for mortgage servicing rights
      at any of the reporting dates. Amortization of MSRs is based upon
      individual loan-level activity versus estimates for the portfolio as a
      whole. Loan-level amortization includes the monthly amortization of a
      portion of the MSR balance for each "active" loan, as well as full
      amortization of the MSR balance for any loan that prepays during the
      month. Accordingly, it is less likely that a valuation allowance for MSRs
      would be required as a result of falling interest rates since the
      amortization method captures accelerated payments on a monthly basis.

      YOUR ACCOUNTING POLICY FOR LOANS TO STATE HOW THESE LOANS ARE ACCOUNTED

      Chart Bank actually does not originate fixed-rate residential mortgages
      for its own portfolio and then subsequently sell them; instead it has
      arrangements whereby it originates fixed rate mortgage loans in the
      capacity of a loan broker for other lenders. A loan originated under such
      an arrangement is closed in the other lender's name, and Chart Bank
      receives a loan brokerage fee for its brokerage services. The Registration
      Statement has been clarified accordingly. See Amendment No. 1, page 133.

                     IMPAIRMENT ASSESSMENT EXPLANATION CODE

A. For U.S. Government and Agency securities: As of September 30, 2004,
management has reviewed Benjamin Franklin Bancorp's financial prospects, its
likely growth targets and its existing sources of liquidity including its
borrowing capacity, and has determined that it has both the intent and the
ability to hold these securities until they mature. Because these are U.S.
Government guaranteed obligations, there is no concern that there will be a loss
of either principal or interest in the remaining period until maturity. As of
September 30, 2004, unrealized losses aggregated .53% of the amortized cost of
these securities.

B. For Corporate Bonds: As of September 30, 2004, management has reviewed
Benjamin Franklin Bancorp's financial prospects, its likely growth targets and
its existing sources of liquidity including its borrowing capacity, and has
determined that it has both the intent and the ability to hold these securities
until they mature. Because these corporate bonds are all "A" rated as of
September 30, 2004 and because the remaining time to maturity is relatively
short (less than 2 years), management considers it highly unlikely that there
would be any loss of either principal or interest in the time remaining until
maturity. As of September 30, 2004, unrealized losses aggregated .58% of the
amortized cost of these securities.

C. For Mortgage-backed Securities, consisting primarily of Collateralized
Mortgage Obligations ("CMOs"): Benjamin Franklin purchased its CMO portfolio,
with an original value of $99.4 million, in 2002 and 2003 as part of its
strategy to enhance earnings from its investment portfolio while providing
ongoing liquidity. That portfolio has since provided principal pay-downs in line
with management's expectations, aggregating $45.5 million, or 45.8% of the
original purchase amounts, over the past two years. Management, after reviewing
Benjamin Franklin's financial prospects, growth targets, and its existing
sources of liquidity including its borrowing capacity, has determined that it
has both the intent and ability to hold these remaining CMO and other MBS
investments until their final maturity. The unrealized losses, which aggregate
3.6% of amortized cost at September 30, 2004, will continue to exist as market
rates remain above the purchase yields of the individual securities. However,
these investments are supported by underlying residential mortgage loan
collateral as well as guarantees by the issuers of these investments--Freddie
Mac, Fannie Mae or Ginnie Mae. Thus, management considers that there is no risk
of loss of either principal or interest in the time remaining until final
maturity.
