Louisiana Highway 411 (LA 411) is a north–south state highway in Louisiana.
LA 411 begins at the intersection of Louisiana Highway 76 in Rosedale, running north on the eastern banks of a Mississippi River canal runoff, with LA 77 running on the west side of the canal. Six miles from the southern terminus, LA 411 passes by the eastern edges of Maringouin. After leaving the town limits, LA 411 crosses the Iberville Parish/Pointe Coupee parish line, and continues north for 5.4 miles (8.7 km), until LA 411 reaches the northern terminus at an intersection with US 190/Louisiana Highway 78 in Livonia, Louisiana.
The roadway itself continues south from the southern terminus becoming Sidney Road and eventually intersecting Interstate 10.
