Pierre Rabhi (born Rabah Rabhi; 29 May 1938 – 4 December 2021) was a French writer, farmer, and environmentalist. Originally a Muslim, he converted to Christianity before abandoning that religion as well.

Rabhi studied in France, and is considered an important figure in French agroecology. He invented the concept of an oasis en tous lieux ("an oasis in any place"). Rabhi advocated a society which respects its population and land, supporting the development of agricultural techniques which preserve natural resources.
