The following is a list of state highways in the U.S. state of Louisiana designated in the 1-50 range prior to the 1955 Louisiana Highway renumbering. All were part of the original 98 state highways authorized by the state legislature in 1921.

Louisiana State Route 3 ran 153.4 miles (246.9 km) in a north–south direction from Baton Rouge to the Arkansas state line north of Lake Providence. The designation existed in two segments as the roadway passed through the state of Mississippi between a point north of St. Francisville and Vidalia (opposite the Mississippi River from Natchez, Mississippi). North of Vidalia, the route also passed through St. Joseph, Newellton, and Tallulah.

In 1926, the southern segment became part of US 61, and the northern segment became part of US 65 when the numbered U.S. Highway system was created. Route 3 remained co-signed with its U.S. counterparts until the 1955 Louisiana Highway renumbering, which eliminated such overlaps. A portion of the route north of Lake Providence bypassed in the 1930s was designated as Route 3-D while it remained in the state highway system.
