Pusa is a genus of the earless seals, within the family Phocidae. The three species of this genus were split from the genus Phoca, and some sources still give Phoca as an acceptable synonym for Pusa.

The three species in this genus are found in Arctic and subarctic regions, as well as around the Caspian Sea. This includes these countries and regions: Russia, Scandinavia, Britain, Greenland, Canada, the USA, Iran, Azerbaijan, Kazakhstan, and Japan.

Only the Caspian seal is endangered.
