Lontra is a genus of otters from the American continent.

The genus comprises four species:

• Northern River Otter (Lontra canadensis)
• Southern River Otter (Lontra provocax)
• Long-tailed Otter (Lontra longicaudis)
• Marine Otter (Lontra felina)

These species were previously included in the genus Lutra, together with the European Otter, but they have now been moved to a separate genus, because they are more closely related to the genera Lutrogale and Pteronura than to the other species in Lutra.
