                            FORM N-CSR CERTIFICATION

I, Brian S. Shlissel, certify that:

          1. I have reviewed this report on the Form N-CSR of the PIMCO
Municipal Income Fund II;

          2. Based on my knowledge, the 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 the report;

          3. Based on my knowledge, the financial statements, and other
financial information included in this report, fairly present in all material
respects the financial condition, results of operations, changes in net assets,
and cash flows (if the financial statements are required to include a statement
of cash flows) of the registrant as of, and for, the periods in this report:

          4. The registrant's other certifying officers and I are responsible
for establishing and maintaining disclosure controls and procedures (as defined
in Rule 30a-3(c) under the Investment Company Act of 1940) and internal control
over financial reporting (as defined in Rule 30a-3(d) under the Investment
Company Act of 1940) for the registrant and 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 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 a date within 90 days prior to the filing date of
          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 half-year (the registrant's second
          fiscal half-year in the case of an annual report) 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 officers and I have disclosed to
the registrant's auditors and the audit committee of the registrant's board of
directors (or persons performing the equivalent functions):

                    (a) All significant deficiencies and material weaknesses in
          the design or operation of internal control over financial reporting
          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 controls over financial reporting.
