The Hajen class, also known as the Hajen III class, was a series of submarines built by Kockums and operated by the Swedish Navy. The design was influenced by the German Type XXI submarine. A total of six submarines were built between 1954 and 1958 and were kept in service until 1980.

The first Hajen-class submarine to be built was HSwMS Hajen in 1954, followed by HSwMS Sälen (1955), HSwMS Valen (1955), HSwMS Illern (1957), HSwMS Bävern (1958), and HSwMS Uttern (1958).
