Summit is a town in Pike County, Mississippi, United States. The population was 1,705 at the 2010 census. It is part of the McComb, Mississippi Micropolitan Statistical Area. The town originated as a railroad town and was named Summit because it was thought to be the highest point on the Illinois Central Railroad between New Orleans and Jackson, Tennessee. However, nearby Brookhaven has that distinction. It was the birthplace of the "Summit Trio", a group of three women artists in the 1960s.
