Swedish Maritime Administration, Maritime administration facility in Norrköping, Sweden

The Swedish Maritime Administration (Sjöfartsverket) is a government agency headquartered in Norrköping since 1975. It keeps sea lanes open and safe through pilotage, fairway maintenance, icebreaking, hydrography, and maritime search and rescue, and it maintains Sweden's lighthouses and other aids to navigation. It runs the Joint Rescue Center Gothenburg and owns five icebreakers.

A 1950 government inquiry into how Sweden's scattered maritime resources could be used led to the Kungliga Sjöfartsstyrelsen, created on 1 January 1956 from the Pilotage Service and the Hydrographic Office, plus parts of the Road and Hydraulic Engineering Works and the state icebreaker service. It was renamed Sjöfartsverket in 1969, became an affärsverk in 1987, and moved from Stockholm to Norrköping in 1975.

Since the early 2000s the agency has run the Swedish Seamen's Library, taken over from the dissolved Swedish Government Seamen's Service (HKF). Its headquarters and icebreaker management sit in Norrköping, while the Joint Rescue Center Gothenburg handles sea and air rescue. Ten pilot areas line the coast, from Luleå to Marstrand and Vänern/kanalen.

The head office sits in Norrköping, where the icebreaker command also directs operations; the agency's regional units are strung along the coast and the large inland lakes, with ten pilot areas from Luleå to Vänern/kanalen. The Joint Rescue Center Gothenburg and the helicopter operations' head office are in Gothenburg. The Swedish Seamen's Library is among the activities the agency took over.

The agency owns five icebreakers and can call on three more; since 2000 their operation has been contracted out, first to the Norwegian joint venture Trans Viking Icebreaking & Offshore, later to Viking Supply Ships AS. The current contract was signed in 2015 and runs to 2022.
