The Marinens Flyvebaatfabrikk M.F.7 was a two-seat biplane floatplane built by the Royal Norwegian Navy Air Service aircraft factory Marinens Flyvebaatfabrikk in 1923. The M.F.7 was designed and employed as a trainer aircraft, and functioned as a temporary solution until a better aircraft was designed. Soon after it entered service, the aircraft factory's experience with the M.F.7 led to the construction of the Marinens Flyvebaatfabrikk M.F.8, which remained in service as the main trainer aircraft of the Royal Norwegian Navy Air Service until the German invasion of Norway in 1940.
