Négra Lock (French: écluse de Négra) is a single chamber lock on the Canal du Midi near the village of Villefranche-de-Lauragais in Languedoc, France. There is a small chapel at the lock and also a small red-brick aqueduct which carries the canal over the Thésauque, a tributary of the Hers.
Négra Lock is at an altitude of 166m and is ascending when travelling west - east. The adjacent locks are Laval Lock to the east and Sanglier Lock to the west.
