         investment decision with respect to the issuance of Suncoke shares.

4.       You disclose in your December 31, 2018 Form 10-K that AK Steel intends
to permanently
         close its Ashland Works Plant by the end of 2019 and you believe AK
Steel has not and
         would not satisfy the second criterion of the termination clause.
Based on your disclosure
         on page 73 therein, AK Steel accounted for 26% of your sales and other
operating revenue
         for 2018. Please tell us whether AK Steel has terminated or intends to
terminate their
         take-or-pay supply agreements with you. If so, please amend your
filing to discuss the
         potential negative impact to sales and cash flows. Refer to Sections
501.12.b. and
         501.13.a. of the Financial Reporting Codification for guidance. If you
continue to believe
         that AK Steel has not and would not satisfy the second criterion of
the termination clause,
         please amend your filing to disclose the facts and circumstance
supporting your
         conclusion.
5.       We note your forum selection provision. Please disclose that such a
provision may limit a
         shareholder's ability to bring a claim in a judicial forum that it
finds favorable for disputes
         with the company and its directors, officers, or other employees and
may discourage
         lawsuits with respect to such claims.

6.       Please expand your discussion of both SunCoke Energy, Inc. and SunCoke
Energy
         Partners, L.P.'s reasons for the merger to quantify the cited benefits
and negative factors.

7.     Please provide a pre-Transaction organization chart of the consolidated
entity, SunCoke
       Energy, Inc. as well as as a chart of all entities after the Transaction
has been completed.
       After consummation, disclose the legal status of SXCP, i.e., whether it
will remain a
       partnership as a wholly owned subsidiary of SunCoke. Explain how you
have
       considered, if at all, the Final Regulations described in further detail
in the December 31,
       2018 Forms 10-K of SunkCoke and SXCP, in your pro forma accounting for
income
       taxes. In this regard, we note that pursuant to the Final Regulations, a
limited partnership
       will be taxed retroactively as if it were a corporation at federal and
state tax rates at the

entity, explain

8.       We note that your forum selection provision identifies the Court of
Chancery of the State
         of Delaware (or other state court located within the State of Delaware
or, if no state court
         located within the State of Delaware has jurisdiction, then the
federal district court for the
         District of Delaware) as the exclusive forum for certain litigation,
including any
         "derivative action." Please disclose whether this provision applies to
actions arising under
         the Securities Act or Exchange Act. If so, please also state that
there is uncertainty as to
         whether a court would enforce such provision. If the provision applies
to Securities Act
         claims, please also state that stockholders will not be deemed to have
waived the
         company's compliance with the federal securities laws and the rules
and regulations
         thereunder. In that regard, we note that Section 22 of the Securities
Act creates concurrent
         jurisdiction for federal and state courts over all suits brought to
enforce any duty or
         liability created by the Securities Act or the rules and regulations
thereunder.
Unaudited Pro Forma Condensed Consolidated Financial Statements, page F-2

9.       As disclosed herein, since the SunCoke historical financial
information includes the
         accounts of SXCP, the historical financial information of SXCP has not
been shown
         separately. As such, please provide tables of the major captions
included in the pro forma
         financial statements that reconcile SXCP historical data to SunCoke
data, i.e., the first
         column in the pro forma financial statements, and identify and
describe material
         reconciling items. For example, explain the makeup of the $558.8
million difference
         between SXCP sales as of December 31, 2018 of $892.1 million to the
$1,450.9 million in
         sales for the consolidated entity presented on page F-4. The
description of the merger
         parties on page 84 does not appear to provide information specific
enough
         to sufficiently distinguish between the nature of the two businesses.
In this regard, it may
         help to list the facilities owned, leased and/or operated by each
entity and to describe the
         activities conducted at each, identifying any overlap as necessary.
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.

       Refer to Rules 460 and 461 regarding requests for acceleration. Please
allow adequate
time for us to review any amendment prior to the requested effective date of
the registration
statement.
