Sténio Joseph Vincent (French pronunciation: [stenjo ʒozɛf vɛ̃sɑ̃]; February 22, 1874 – September 3, 1959)[1] was President of Haiti from November 18, 1930 to May 15, 1941.

From 1915 to 1934 Haiti was occupied by U.S. Marines; the United States had intervened after the murder of President Vilbrun Guillaume Sam.

Vincent had enjoyed a cooperative relationship with and financial support from the government of Dominican President Rafael Trujillo.

After two years of relative quiet in Port-au-Prince, Vincent's failure to press for justice for the slain workers prompted protests in the capital.

United States president Franklin D. Roosevelt took the case to the Dominican government, which agreed in 1938 to compensate the slain workers’ relatives the following year.
