Sobo-Katamuki Quasi-National Park (祖母傾国定公園) was a Quasi-National Park in Ōita and Miyazaki Prefectures, Japan. It was in 2017 incorporated in to the Sobo, Katamuki and Okue Biosphere Reserve.

Established in 1965, the park derived its name from Mount Sobo (1756 m) and Mount Katamuki (傾山) (1602 m). The Quasi-National Park borders two homonymous Prefectural Parks, namely the Sobo Katamuki Prefectural Natural Park (Ōita) and Sobo Katamuki Prefectural Natural Park (Miyazaki).
