Louisiana Highway 19 (LA 19) is a state highway located in southeastern Louisiana. It runs 33.93 miles (54.61 km) in a north–south direction from U.S. Highway 61 (US 61) in Baton Rouge to the Mississippi state line north of Norwood.

The route connects a string of communities projecting northward out of Baton Rouge, the state capital, including the small suburban cities of Baker and Zachary. It traverses two of the Florida Parishes, East Baton Rouge and East Feliciana, in a nearly linear fashion as the entire route parallels a railroad line.

LA 19 has three notable junctions, two of which provide access to downtown Baton Rouge. These are US 61 and Interstate 110 (I-110) and are located within the first 1.0 mile (1.6 km) of the route on its southern end. The highway also intersects LA 10, an east–west cross-state route that connects with Jackson and Clinton, two nearby small towns of historic character. The latter is also the seat of East Feliciana Parish. The remaining junctions along LA 19 mostly serve to connect the route with the parallel US 61 and LA 67.
