Pétion-Ville (Haitian Creole: Petyonvil) is a commune and a suburb of Port-au-Prince, Haiti, in the hills east and separate from the city itself on the northern hills of the Massif de la Selle. Founded in 1831 by president Jean-Pierre Boyer, it was named after Alexandre Sabès Pétion (1770–1818), the Haitian general and president later recognized as one of the country's four founding fathers. The district is primarily a residential and touristic area. It had a population of 283,052 at the 2003 Census, which was officially estimated to have reached 376,834 in 2015. Many diplomats, foreign merchants and wealthy people who engage in business reside in Pétion-Ville. Despite the distance from the capital and the general affluence of the district, the lack of administrative enforcement has led to the formation of shantytowns on the outer edges of the district, as poor locals migrate upward and have settled there in search of job opportunities.

The St. Jean Bosco massacre took place in Haiti on 11 September 1988. At least 13 people (it is impossible to say how many; some sources say 50) were killed and around 80 wounded in a three-hour assault on the Saint-Jean Bosco church in Port-au-Prince, which saw the church burned down. The church was the parish of future President Jean-Bertrand Aristide, then a liberation theology Roman Catholic priest of the Salesians of Don Bosco order, and had been packed with 1000 people for Sunday mass. Aristide, who had survived at least six attempts on his life after a fiery 1985 Mass had helped spark the unrest which eventually led to the 1986 overthrow of the dictator Jean-Claude Duvalier, was evacuated from the church into a residence inside the church compound. According to the Inter-American Commission on Human Rights, the following day, "five men and one woman appeared on the government controlled television station (Télé Nationale) and admitted their participation in the attack on the church. They threatened a 'heap of corpses' at any future mass celebrated by Aristide. Many people were outraged that these individuals could appear on television, without any disguise, confess their participation in these events and threaten future criminal acts with no fear of being arrested by the authorities." The massacre contributed to the emergence a week later of the September 1988 Haitian coup d'état against the Henri Namphy regime, which brought to power Prosper Avril. In 1993 Antoine Izméry was assassinated at a mass commemorating the massacre.
