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.
