Louisiana Highway 74 (LA 74) is a state highway located in southeastern Louisiana. It runs 10.67 miles (17.17 km) in an east–west direction from LA 75 in St. Gabriel to U.S. Highway 61 (US 61) north of Gonzales.
Much of LA 74 traverses a string of newer residential subdivisions growing out of the Baton Rouge metropolitan area. The route roughly parallels LA 30 for its entire distance. LA 30 and LA 74 terminate at opposite ends of Gonzales with neither highway running directly into the center of town. However, LA 30 provides access to Interstate 10 (I-10), connecting to Baton Rouge and New Orleans, whereas LA 74 does not.
