WPoint Fortin, officially the Republic Borough of Point Fortin, the smallest Borough in Trinidad and Tobago is located in southwestern Trinidad, about 32 km (20 mi) southwest of San Fernando, in the historic county of Saint Patrick.

After the end of the oil boom Point Fortin was hit hard by economic recession in the 1980s and the closure of its oil refinery. Construction of a Liquefied Natural Gas plant by Atlantic LNG in late 1990s boosted the economy.
