Osa Maliki Wangsadinata (30 December 1907 – 15 September 1969) was an Indonesian politician who served as the chairman of the Indonesian National Party (PNI) and a deputy speaker of the People's Consultative Assembly (MPR) from 1966 until his death. Born in Padalarang, Osa was educated at a Taman Siswa school. He participated in an unsuccessful communist rebellion against the colonial government in 1926, being exiled to the Boven-Digoel concentration camp as a result. After returning from exile in 1938, he worked as a teacher. During the Japanese occupation, Osa worked in the propaganda section of a Hōkōkai and became a member of the Suishintai, however, he was briefly detained by the Kenpeitai over his connections to an underground resistance movement.

Following the proclamation of Indonesian Independence in 1945, Osa served in various positions in the newly-formed Republican government. During the Indonesian National Revolution, he co-founded a political party, the Indonesian People's Union (SRI), which was merged to form the PNI. In 1947, he was imprisoned by the Dutch shortly after Operation Product, but was released following the signing of the Renville Agreement a year later. He remained politically active following the recognition of sovereignty by the Dutch in 1949, and was elected to the People's Representative Council (DPR) in 1955. His support of the previous parliamentary system and opposition to President Sukarno's Guided Democracy led to a power struggle within the PNI, between Osa's right-wing and Ali Sastroamidjojo's left-wing. However, following the fall of Sukarno, Osa was elected party chairman, ousting Ali. As chairman, Osa attempted to reform the PNI. He died of a heart attack on 15 September 1969 in Semarang, Central Java.
