RE:	National Mercantile Bancorp
Form 8-K
Filed June 22, 2005
File No. 1-13015

Dear Mr. Brown,

	We have reviewed the above referenced filing for compliance
with
the requirements of Form 8-K and have the following comment:

* Please amend your report to specifically include the interim
period
subsequent to your fiscal year end through the date of your
independent auditors` resignation in your "no disagreements"
disclosure in the second paragraph.  Refer to Item 304(a)(1) of
Regulation S-B.

	We urge all persons who are responsible for the accuracy and
adequacy of the disclosure in the filing to be certain that the
filing includes all information investors require for an informed
decision.  Since the company and its management are in possession
of
all facts relating to a company`s disclosure, they are responsible
for the accuracy and adequacy of the disclosures they have made.

	In connection with responding to our comment, please provide,
in
writing, a statement from the company acknowledging that:

* the company is responsible for the adequacy and accuracy of the
disclosure in the filing;

* staff comments or changes to disclosure in response to staff
comments do not foreclose the Commission from taking any action
with
respect to the filing; and

* the company may not assert staff comments as a defense in any
proceeding initiated by the Commission or any person under the
federal securities laws of the United States.

	In addition, please be advised that the Division of
Enforcement
has access to all information you provide to the staff of the
Division of Corporation Finance in our review of your filing or in
response to our comment on your filing.

	Please file an amendment via EDGAR in response to this
comment
within five business days or contact us immediately if you require
additional time. Such amendment should be filed under cover of
Form
8-KA and should include the Item 4.01 designation. A letter from
your
former accountant addressing the revised disclosures should also
be
included in your amended Form 8-KA and filed as Exhibit 16.

Please contact me at (202) 551-3437 if you have any questions.


Sincerely,


Michael C. Volley
Staff Accountant
