Wisner is a town in Franklin Parish, Louisiana, United States. The population was 964 at the 2010 census, down from 1,140 in 2000.
Wisner was founded[when?] by Edward Wisner, a native of Athens, Michigan, whose family came from Switzerland and originally settled in Orange County, New York, in the early 1700s.
The Holly Grove Colored Baptist Church in Wisner was established in the post-slavery period after the Civil War through the work of pastor Eldridge King David Swayzer. One of Swayzer's descendants, Frances Swayzer Conley, an English professor at Bossier Parish Community College in Bossier City and a resident of Shreveport, has written a pictorial family history entitled Home to Holly Grove: Cherishing Our Rich Heritage.
