Louisiana Highway 89 (LA 89) is a state highway located in southern Louisiana. It runs 12.74 miles (20.50 km) in a north–south direction from LA 14 in Delcambre to an intersection with Church Street in Youngsville.

The highway parallels the Vermilion–Iberia parish line from Delcambre, a small town partially located in both parishes, to a junction with LA 88 at Lozes. LA 89 then makes a turn into Lafayette Parish and proceeds to Youngsville, a small city and growing bedroom community of nearby Lafayette. Along its route, the highway passes through a mixture of sugar cane fields, older rural residential development, and newer suburban development.

LA 89 was created in the 1955 Louisiana Highway renumbering from portions of several former state routes. Through most of its existence, the route continued north from Youngsville to a junction with U.S. Highway 90 (US 90) between Lafayette and Broussard. This northern segment became LA 89-1 in 2013 when a portion of the route in Youngsville was transferred to the city following a highway improvement project, which created a gap in state maintenance. In the future, the entire corridor is proposed to be turned over to local control as part of the Louisiana Department of Transportation and Development (La DOTD) road transfer program.
