The town was formed in 1799 before Franklin County was established, from parts of the towns of Champlain and Plattsburgh. By 1802, Chateaugay comprised most of Franklin County. Subsequently, its territory was reduced to form other towns. The town of Malone was set off from Chateaugay in 1805. When Franklin County was established from Clinton County, part of Chateaugay remained in Clinton County. The town of St. Armand was taken off in 1822 and placed in Essex County. The remaining three towns derived from Chateaugay remained in Franklin County: Bellmont (1833) and Franklin (taken from Bellmont in 1834), and Burke (1844).
