Cross Bayou is a 38-mile-long (61 km) river in Texas and Louisiana. It is a tributary of the Red River, part of the Mississippi River watershed. It rises in southeastern Harrison County, Texas, 15 miles (24 km) southeast of Marshall, and flows east into Caddo Parish, Louisiana. It flows through 8-mile-long (13 km) Cross Lake on the outskirts of Shreveport, and joins the Red River in downtown Shreveport. The latter portion is known as Twelve Mile Bayou, locally spelled Twelvemile Bayou.
