Frantz Casseus (1915–1993) was a Haitian guitarist and composer.Although born and raised in Port-au-Prince, Haiti he spent most of his adult life in the United States. His music maintained a focus on Haitian folk forms, which he incorporated into his recordings and his published compositions. Casseus was also an early guitar teacher to the musician Marc Ribot, who has played a significant role in preserving Casseus' musical legacy. As part of these efforts, Ribot edited a collection of Casseus' solo guitar compositions, and performed those same pieces on a CD issued in 1993.
