Louisiana Highway 4 (LA 4) is a state highway located in northern Louisiana. It runs 164.54 miles (264.80 km) in an east–west direction from U.S. Highway 71 (US 71) at Loggy Bayou to LA 605 in Newellton.

The entire route parallels Interstate 20 (I-20) an average of about 20 miles (32 km) to the south. Along the way, it serves the city of Winnsboro and smaller towns such as Ringgold, Jonesboro, Chatham, Columbia, and Newellton (its eastern terminus). It also intersects many of the state's major north–south routes, such as US 71 (its western terminus), US 371, US 167, US 165, US 425, and US 65.

Though it runs primarily east–west, LA 4 meanders along rural roads for virtually its entire distance, bending considerably to the north and south in order to pass through the centers of various towns. LA 4 travels through five parishes, connecting the parish seats of the middle three (Jackson, Caldwell, and Franklin). Not quite a cross-state route, it begins at US 71 southeast of the Shreveport-Bossier City Metropolitan Area about 36 miles (58 km) east of the Texas state line and does not reach I-49, Louisiana's major north–south interstate. Its eastern terminus, however, comes within five miles (8.0 km) of the Mississippi state line at the Mississippi River.
