Louisiana Highway 10 (LA 10) is a state highway located in southern Louisiana. It runs 255.51 miles (411.20 km) in an east–west direction from U.S. Highway 171 (US 171) south of Leesville to the Mississippi state line east of Bogalusa.

The route connects a string of small towns and cities across the Central Louisiana, Acadiana, and Florida Parishes regions of the state. It runs parallel and to the north of the busier US 190 corridor. LA 10 crosses the Mississippi River via the John James Audubon Bridge, the only such crossing between Baton Rouge and Natchez, Mississippi. The western terminus in Vernon Parish comes within 15 miles (24 km) of reaching the Sabine River at the Texas state line and making LA 10 a true cross-state route.

During its lengthy route, LA 10 traverses ten parishes and connects six parish seats, including Ville Platte, New Roads, St. Francisville, Clinton, Greensburg, and Franklinton. It also passes through the cities of Oakdale and Bogalusa as well as towns such as Washington and Jackson. LA 10 intersects most of the state's major north–south highways, including Interstate 49 (I-49), Interstate 55 (I-55), US 51, US 61, US 71, US 165, US 167, and US 171.

Since the end of 2010, LA 10 has existed in two disconnected sections as the Melville Ferry service across the Atchafalaya River was discontinued. The nearest bridge crossing is on US 190 at Krotz Springs, 16.5 miles (26.6 km) to the south via LA 77 and LA 81. Alternately, motorists may cross the river via LA 1 at Simmesport, 21.5 miles (34.6 km) to the north.
