Louisiana Highway 99 (LA 99) is a state highway located in southwestern Louisiana. It runs 32.44 miles (52.21 km) in a north–south direction from LA 14 west of Lake Arthur to U.S. Highway 190 (US 190) east of Kinder.

The highway bisects the sparsely populated Jefferson Davis Parish as it zigzags along rural section line roads. Roughly halfway along its route, LA 99 passes through the town of Welsh and an interchange with Interstate 10 (I-10), the region's main east–west highway. It also intersects US 90, an older parallel corridor that now acts largely as a business route in the area.

From the south, LA 99 begins at an intersection with LA 14 approximately 8.5 miles (13.7 km) west of the town of Lake Arthur. Signs direct motorists to the nearby Lacassine National Wildlife Refuge located to the south. LA 99 proceeds due north as an undivided two-lane highway in a rural area of southern Jefferson Davis Parish. After 2.0 miles (3.2 km), it intersects LA 380, which passes through the small community of Thornwell. After another 2.0 miles (3.2 km), the highway curves east briefly then back to the north amidst a small cluster of farm houses. LA 99 crosses a bridge over Bayou Chene then intersects LA 1126 a distance of 2.8 miles (4.5 km) later.
