Jimmy Chérizier (French pronunciation: [dʒimi ʃeʁizje]; born 30 March 1977), nicknamed Barbecue (Haitian Creole: Babekyou), is a Haitian rebel and gang leader, former policeman, and warlord who is the head of the Revolutionary Forces of the G9 Family and Allies (Haitian Creole: Fòs Revolisyonè G9 an Fanmi e Alye), abbreviated as "G9" or "FRG9", a federation of over a dozen Haitian gangs and armed groups based in Port-au-Prince. Known for often making public appearances in military camouflage and a beret, he calls himself the leader of an "armed revolution". Considered the most powerful warlord in Haiti, he is currently believed to be one of the country's most powerful political figures.

In early March 2024, the Revolutionary Forces of the G9 Family and Allies staged the largest jailbreak in Haitian history and escalated attacks across the country, including an attempted siege of the Toussaint Louverture International Airport. Chérizier claimed responsibility for the attacks and stated that the goal was to capture key government institutions, overthrow the unelected acting prime minister Ariel Henry and become more powerful in Haiti, warning that "if Ariel Henry doesn't step down and the international community continues to support him, they will lead us directly to a civil war which will end in genocide." Henry announced his intention to resign on 11 March 2024, and did so on 24 March of that year.

Jimmy Chérizier was born in Delmas, Ouest, which is located in the Port-au-Prince Arrondissement, next to the slums of La Saline, Port-au-Prince. He was one of eight children. His father died when he was five years old. Chérizier's mother worked as a fried chicken vendor during his childhood, which he claims to be origin of his nickname "Barbecue"; others, however, claim it originated from allegations of him setting people on fire during massacres, which he denies.

Chérizier was a police officer for the Haitian National Police. Chérizier belonged to the Unité Départementale pour le Maintien de l'Ordre (UDMO, "Unit for the Maintenance of Order"), a special unit within the Haitian National Police.

While he was a police officer, Chérizier is alleged to have perpetrated the 2018 La Saline massacre, in which at least 71 people were killed and over 400 homes burned down. He is accused of being involved in the 2017 Grande Ravine massacre that killed at least nine people, and the 2019 Bel Air massacre. In December 2018, Chérizier was fired by the Haitian National Police. Chérizier has denied all allegations, and claims he was in Delmas 6 at the time of the purported massacre. Chérizier became a gang leader in Base Delmas 6, Delmas, Ouest, where he is accused of perpetrating further massacres.

Chérizier is the leader of the Revolutionary Forces of the G9 Family and Allies (G9, Haitian Creole: Fòs Revolisyonè G9 an Fanmi e Alye), a self-described federation of rebel groups. The organization was originally composed of nine groups, but has since grown to include over a dozen. The formation of the G9 was announced by Chérizier in a YouTube video on 10 June 2020, soon after the May 2020 Port-au-Prince massacre.

The G9 is one of about 95 rebellious factions that battle for supremacy in Port-au-Prince. Its stronghold is believed to be the commune of Delmas, Ouest. As of July 2021, it controlled Martissant, Village de Dieu, Grande Ravine, Bel Air, Cité Soleil, Fort Dimanche, and many other areas in Port-au-Prince. These areas give the G9 a hold over the center of Port-au-Prince, as well as northern and southern access points to its metropolitan area, which allow the G9 to isolate Port-au-Prince from the rest of Haiti at its will.

On 12 May 2021, Chérizier was reportedly wounded during a gunfight with a rival group. A Doctors Without Borders facility in Martissant, Port-au-Prince, denied rumors that he had received medical treatment at the facility.
