51 Nemausa () is a large asteroid-belt asteroid similar to 1 Ceres in composition. It was discovered by one "A. Laurent", an obscure figure about whom little is known. Laurent made the discovery from the private observatory of Benjamin Valz in N mes, France. The house, at 32 rue Nationale in N mes, has a plaque commemorating the discovery. With Laurent's permission, Valz named the asteroid after the Celtic god Nemausus, the patron god of N mes during Roman times.^[1]

Nemausa measures 147.9km in diameter.^[2] Lightcurve data suggests that it may have a small moon.^[3] It may have a water content of about 14%.^[4] Nemausa has been studied by radar.^[5]
