Louisiana Highway 138 (LA 138) is a state highway located in Morehouse Parish, Louisiana. It runs 12.74 miles (20.50 km) in a north–south direction from LA 134 south of Collinston to a junction with U.S. Highway 165 (US 165), U.S. Highway 425 (US 425), and LA 2 in Mer Rouge.
A largely rural route, LA 138 connects the small villages of Collinston and Mer Rouge, located northeast of Monroe.
