Louisiana Highway 16 (LA 16) is a state highway located in southeastern Louisiana. It runs 110.27 miles (177.46 km) in a general east–west direction from LA 22 south of French Settlement to LA 21 in Sun.

The route makes a wide arc through the Florida Parishes region of the state, traveling east of Baton Rouge and avoiding the urban centers of Hammond and Covington. However, it passes through a number of the area's smaller towns and communities, such as Denham Springs, Montpelier, Amite City, and Franklinton. Some but not all of the signage south of Watson still bears north–south directionals rather than the standard east–west. Major junctions along the route include U.S. Highway 190 (US 190) in Denham Springs and Interstate 55 (I-55) in Amite City.

LA 16 was designated in the 1955 Louisiana Highway renumbering, stitched together from six shorter former routes, including State Route 131 south of Denham Springs; State Route 103 between Watson and Amite City; and State Route 35 between Amite City and Franklinton.
