Ernst Jean-Joseph (11 June 1948 – 14 August 2020) was a Haitian football midfielder who played for Haiti in the 1974 FIFA World Cup.

[3] Described as a "red-haired mulatto" by Brian Glanville,[4] Jean-Joseph failed a doping test after Haiti's opening match with Italy in 1974.

After first contending that he had received a “lot of pills” from his physician in Haiti for treatment of asthma (and being contradicted by the team doctor, who told the media he had no such ailment), he admitted that he had used a stimulant containing phenmetrazine to improve his performance.

[6] Haitian officials dragged Jean-Joseph out of the Grünwald Sports School in Munich where the team had been staying, beat him, and held him over night at the Sheraton Hotel and flew him back to Haiti.

The terrified Jean-Joseph had made several phone calls to a sympathetic hostess who passed on the information to the designated team attaché, Kurt Renner.
