The Madagascar revolt was an attempted revolution against the French by nationalists on the island of Madagascar between 1947 and 1948.

The Mouvement Democratique de la Renovation Malagache (MDRM), whose objective was independence for Madagascar, formed in 1946 in response to the island becoming a French overseas territory. On March 29, 1947, Malagasy nationalist tribesmen revolted in the eastern part of the island. One third of the island was seized before French soldiers stationed on the island received reinforcements from France, and were able to quell the rebellion. The loss of life was high - more than 11,000 persons died in the fighting, 180 of those reported to be non-Malagasy.

The leaders responsible for the uprising have never been conclusively identified. Although the MDRM leadership consistently maintained its innocence, the party was outlawed by the French. Military leaders of the revolt were tried by the French military and twenty were executed. It is reported that 5,000 to 6,000 convictions were produced in further trials, with penalties ranging from brief imprisonment to death.
