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. The signage for roughly the first  ¹⁄₃ of LA 16 carries north–south directional banners before switching to east–west in Watson. 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.
