Pandalus hypsinotus is a crustacean in the Pandalidae family, ordinarily 10–12.5 centimetres (3.9–4.9 in) in length, but large females may reach 17.5 centimetres (6.9 in). It can be found in the Bering Sea, from the Aleutian Islands to Puget Sound, and in the Sea of Japan at depths of 100–200 metres (330–660 ft).
This species attains maturity as a male, and in varying proportions as a female, in the second year, and becomes a female during the third year. Subsequent survival into the fourth year is very low. Female shrimps carry eggs from November to April.
