Louisiana Highway 33 (LA 33) is a state highway located in northern Louisiana. It runs 44.03 miles (70.86 km) in a southwest to northeast direction from U.S. Highway 80 (US 80) in Ruston to the Arkansas state line north of Marion.

The route begins east of Ruston's downtown area and provides access to one of the city's three interchanges with Interstate 20 (I-20). Midway along its route, LA 33 joins LA 15 across Lake D'Arbonne, a popular recreational spot, and through the adjacent town of Farmerville. North of Marion, the roadway continues as Arkansas Highway 129 toward Huttig, Arkansas.

LA 33 was designated in the 1955 Louisiana Highway renumbering, replacing portions of three routes: State Route 44, State Route 11, and State Route 156. This created a single highway designation connecting the seats of Lincoln and Union parishes to each other and with the Arkansas state line.
