EXHIBIT 31.2

                                  CERTIFICATION

I, KEVIN W. LAUDENSLAGER, TREASURER, certify, that:

         1. I have reviewed this quarterly report on Form 10-Q of Mid Penn
Bancorp.

         2. Based on my knowledge, the quarterly report does not contain any
untrue statement of a material fact or omit to state a material fact necessary
to make the statements made, in light of the circumstances under which such
statements were made, not misleading with respect to the period covered by this
quarterly report.

         3. Based on my knowledge, the financial statements, and other financial
information included in this quarterly report, fairly present in all material
respects the financial condition, results of operations and cash flows of the
registrant as of, and for, the periods presented in this quarterly report.

         4. The registrant's other certifying officer and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial
reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the
registrant and we have:

            (a) designed such disclosure controls and procedures, or caused such
                disclosure controls and procedures to be designed under our
                supervision, to ensure that material information relating to the
                registrant, including its consolidated subsidiaries, is made
                known to us by others within those entities, particularly during
                the period in which this quarterly report is being prepared;

            (b) designed such internal control over financial reporting, or
                caused such internal control over financial reporting to be
                designed under our supervision, to provide reasonable assurance
                regarding the reliability of financial reporting and the
                preparation of financial statements for external purposes in
                accordance with generally accepted accounting principles;

            (c) evaluated the effectiveness of the registrant's disclosure
                controls and procedures and presented in this report our
                conclusions about the effectiveness of the disclosure controls
                and procedures, as of the end of the period covered by this
                report based on such evaluation; and

            (d) disclosed in this report any change in the registrant's internal
                control over financial reporting that occurred during the
                registrant's most recent fiscal quarter that has materially
                affected, or is reasonably likely to materially affect, the
                registrant's internal control over financial reporting; and

         5. The registrant's other certifying officer and I have disclosed,
based on our most recent evaluation of internal controls over financial
reporting, to the registrant's auditors and the audit committee of registrant's
board of directors (or persons performing the equivalent function):

            (a) all significant deficiencies in the design or operation of the
            internal controls which are reasonably likely to adversely affect
            the registrant's ability to record, process, summarize and report
            financial information; and

            (b) any fraud, whether or not material, that involves management or
            other employees who have a significant role in the registrant's
            internal control over financial reporting.
