Tsugaru Quasi-National Park (津軽国定公園) is a quasi-national park in Aomori Prefecture in the far northern Tōhoku region of Honshū in Japan. It is rated a protected landscape (category V) according to the IUCN. The park includes a number of discontinuous areas on Tsugaru Peninsula, including the volcanic peaks of Mount Iwaki, a portion of the primeval Siebold's beech forests of Shirakami-Sanchi UNESCO World Heritage Site, Cape Tappi, other coastal areas of northern Tsugaru Peninsula, and the wetlands of Juniko and Jusanko lakes and marshes. The area was designated a quasi-national park on 31 March 1975. It spans the borders of the municipalities of Hirosaki, Goshogawara, Tsugaru, Imabetsu, Sotogahama, Ajigasawa, Fukaura, and Nakadomari. Like all quasi-national parks in Japan, the park is managed by the local prefectural government, in this case, that of Aomori Prefecture.
