Samuel de Missy (Samuel, Pierre, Joseph, David, de Missy or Demissy, 30 October 1755 – 20 October 1820) was a French trader and businessman, from the city of La Rochelle, where he was born.
In February 1794, the National Assembly legislated the Universal Emancipation decree, which effectively freed all colonial slaves.
The Collège Samuel de Missy in La Rochelle is named after him.
