The Fourche Maline culture (pronounced foosh-ma-lean) is a Woodland Period Native American culture that exists from 300 BCE to 800 CE, in what are now defined as southeastern Oklahoma, southwestern Arkansas, northwestern Louisiana, and northeastern Texas.

They are considered to be one of the main ancestral groups of the Caddoan Mississippian culture, along with the contemporaneous Mill Creek culture of eastern Texas.

This culture is named for the Fourche Maline Creek, a tributary of the Poteau River.

Their modern descendants are the Caddo Nation of Oklahoma.
