I, JOHN V. MURPHY, certify that:
   --------------

1.   I have reviewed this report on Form N-CSR of Oppenheimer International
     Growth Fund;

2.   Based on my knowledge, this 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
     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
     presented 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 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
     trustees (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 control over financial
     reporting.
