Chūō Alps Quasi-National Park is a Quasi-National Park in southern Nagano Prefecture, Japan. Established in 2020, the park has an area at time of foundation of 351.16 square kilometres (135.58 sq mi), corresponding exactly to that of the former Chūō Alps Prefectural Natural Park (中央アルプス県立自然公園), founded on 22 November 1951, which it supersedes and replaces. The Park's central feature is the Central Alps. Three separate areas of the park span the borders of thirteen municipalities: Achi, Agematsu, Iida, Iijima, Ina, Kiso, Komagane, Matsukawa, Miyada, Nagiso, Ōkuwa, Shiojiri, and Takamori.
