Ernst Julmé, known by his alias Ti Greg ("Little Greg" in Haitian Creole), was a Haitian gang leader. He was the head of the Delmas 95 gang active in the Delmas and Pétion-Ville suburbs of Port-au-Prince. Before his life of crime, he was an officer of the Haitian National Police (PNH).

The PNH arrested Ti Greg in Pétion-Ville in 2021, but he escaped custody amid a prison break in 2024. A few weeks after his escape, Ti Greg was shot and killed by police in an operation targeting his gang.

Ti Greg was an officer of the Haitian National Police (PNH) before becoming a gang member.

Specialized units of the PNH, including the Departmental Operation and Intervention Brigade, arrested Ti Greg and two other gang members on 7 October 2021, during an evening operation in Pétion-Ville and northern Delmas. Ti Greg was travelling in an unlicensed car, while his two accomplices were on motorcycles. He reportedly attempted to pass himself off as a police officer. The authorities accused Ti Greg of being the leader of the local Delmas 95 gang and committing "several acts of banditry" in the area. Delmas 95 is a member of the Viv Ansanm alliance of gangs, and as such Ti Greg was affiliated its leader, Jimmy "Barbecue" Chérizier.

Ti Greg escaped custody during a storming of his prison by gangs on 3 March 2024. Later that month, on 22 March, he was shot and killed by police in a special operation against Delmas 95 in Pétion-Ville. Ti Greg had attacked police over several days as they attempted to apprehend him. The previous day, Makandal, another prominent gang leader, was killed by vigilantes.
