The Royal Yugoslav Navy (Serbo-Croatian: Кpaљeвcкa Југословенска Pатна Морнарица; Kraljevska Jugoslovenska Ratna Mornarica), was the navy of the Kingdom of Yugoslavia. This navy existed since the establishment of the Kingdom of Serbs, Croats and Slovenes in 1918, which was changed in 1929 to the Kingdom of Yugoslavia. It was disbanded after the Axis invasion in April 1941.
