Winnfield is a small city in, and the parish seat of, Winn Parish, Louisiana, United States. The population was 5,749 at the 2000 census, and 4,840 in 2010. Three governors of the state of Louisiana were from Winnfield.
When Winn Parish was officially formed by the state legislature in 1852, Winnfield was established as the parish seat. During the Civil War, the area around Winnfield was the site of some minor skirmishes. Confederate forces defeated a Union detachment sent to destroy the Cary Salt Works in the area.
Many Civil War bandits made the region their home. Among these were the West and Kimbrill clans, which at one time included Frank and Jesse James.
Three Louisiana governors were Winnfield natives and grew up here: Huey Long, Oscar K. Allen and Earl Long. Huey Long became governor, U.S. Senator. He was assassinated in 1935. Oscar K. Allen was elected governor in 1932. Earl Long, "the Louisiana Longshot," served in a variety of state positions, said to be more than other Louisianan, including elective office.
