The Cortese-Knox-Hertzberg Local Government Reorganization Act of 2000 (Act) is a collection of state laws that govern the changes of organization of local governments in California. The Act begins at Section 56000 of the Government Code, also known as the Local Government Reorganization Act.

The Act establishes procedures for and gives LAFCO power to "approve or, disapprove with or without amendment, wholly, partially or conditionally" proposals concerning the formation of cities and special districts, and other changes in jurisdiction or organization of local governmental agencies. LAFCO is also given authority to make studies of existing governmental agencies in an effort to improve the efficiency of urban services.
