Chugach State Park covers 495,204 acres (2,004 square kilometers) covering a hilly region immediately east of Anchorage, in south-central Alaska.

Established by legislation signed into law on August 6, 1970, by Alaska Governor Keith Miller, this state park was created to provide recreational opportunities, protect the scenic value of the Chugach Mountains and other geographic features, and ensure the safety of the water supply for Anchorage. The park, managed by Alaska State Parks, is the third-largest state park in the United States, and consists of geographically disparate areas each with different attractions and facilities. Only Anza-Borrego Desert State Park in California and Wood-Tikchik State Park in western Alaska are larger. Though primarily in the Municipality of Anchorage, a small portion of the park north of the Eklutna Lake area in the vicinity of Pioneer Peak lies within the Matanuska-Susitna Borough.

Hunting and fishing are permitted in the Chugach under regulations established by the Alaska Department of Fish and Game for game management unit 14c. Target practice is not allowed within the park boundaries.
