The Royal Swedish Naval Materiel Administration^[1] (Swedish: Kungliga Marinförvaltningen, KMF) was the central board of the Swedish Navy in technical and economic terms. It was active between the years 1878 and 1968 when it was disbanded and amalgamated into the Defence Materiel Administration.

The Naval Materiel Administration was established on 1 January 1878 after the approval of the Riksdag and the royal decree, by the transformation of the Management of the Naval Affairs (Förvaltningen av sjöärendena) and the merger between Ministry for Naval Affairs' military and technical agencies. The Naval Materiel Administration consisted of three equal units: the Military Department, the Civil Department and the Engineering Department, each with its own chief but with common office and secretariat. The Naval Materiel Administration acted as the agency under the Ministry for Naval Affairs and was the head board for the defense fleet in military, technical and financial matters. The collegial rule lasted until 1881 when the chief of the entire administration was appointed.^[2] It was until 1920 a government agency under the Ministry for Naval Affairs, then the Ministry of Defence.

In 1968 the Naval Materiel Administration was disbanded and was amalgamated with the Royal Swedish Army Materiel Administration and Royal Swedish Air Force Materiel Administration into the Defence Materiel Administration.^[3]

The Naval Materiel Administration was located in Sparreska palatset at Riddarholmen in Stockholm from 1878 to 1916.^[2] After many years of renting offices in Stockholm it moved to new premises at Banérgatan 62-64 in Stockholm together with the Royal Swedish Army Materiel Administration and Royal Swedish Air Force Materiel Administration. It remained there until it disbanded in 1968.
