Ernst Jean-Joseph (born 11 June 1948) is a Haitian football midfielder who played for Haiti in the 1974 FIFA World Cup. He played for Violette A.C. and Chicago Sting.Soon after Haiti's decent showing against Italy in the tournament - a game in which Jean-Joseph's team had briefly led - celebrations were undermined by his failing of a dope test. Haiti's officials meted out their own punishment before flying the player home.
