The Association of Government Internal Auditors, Inc. (AGIA) is a Non- Government Organization (NGO) that aims to provide quality seminars and trainings to internal auditors in the Philippines. AGIA is an organization that strives for efficiency and effectiveness in the field of internal audit.

AGIA was first organized in 1959 upon the motivation of then Chief Supervising Auditor Cecilio L. Dizon of the General Auditing Office (now COA). In 1962, the Internal Auditing Act (R.A. 3456) was passed requiring internal auditing in the National Government. This was amended in 1965 by R.A. 4177 to include government-owned and/or controlled corporations & local government in its coverage.
