François de Roubaix (French pronunciation: [fʁɑ̃swa də ʁube]; 3 April 1939, Neuilly-sur-Seine, Hauts-de-Seine – 22 November 1975, Tenerife, Canary Islands) was a French film score composer.

Roubaix did not receive any formal education in music, but began studying jazz on his own at age 15, forming a band and learning trombone as an autodidact.

His father, the Oscar-winning filmmaker Paul de Roubaix [fr], who was a producer of the short film, "An Occurrence at Owl Creek Bridge" and the creator of educational films, offered to let François compose scores for the latter.

Notable in his style is his use of folk elements, as well as electronic musical instruments such as synthesizers and early drum machines.

Roubaix had a home studio where he would overdub parts until he was satisfied with the result.
