Jonas Mosa Gwangwa (born 1941 in Orlando East, Soweto) has been an important figure in South African jazz for over 40 years. He first gained significance playing trombone with The Jazz Epistles. After the group broke up he continued to be important to the South African music scene and then later abroad.

In the 1960s he began to gain notice in the United States and in 1965 he was featured in a "Sound Of Africa" concert at Carnegie Hall. The others at the concert included Miriam Makeba, Hugh Masekela, and Letta Mbulu. Despite that he was not seen favorably by the apartheid government so left his homeland in the early 1970s
