Unzen-Amakusa National Park

 is a national park in Nagasaki, Kumamoto, and Kagoshima Prefectures, Japan. Established in 1934, the park derives its name from Mount Unzen, an active volcano at the middle of the Shimabara Peninsula, and the Amakusa islands in the Yatsushiro Sea. The area is closely connected to the early history of Christianity in Japan, and the park encompasses numerous areas related to Kakure Kirishitan.
