HMAS Goorangai was a 223-ton auxiliary minesweeper of the Royal Australian Navy (RAN). She was sunk in an accidental collision with MV Duntroon in 1940, becoming the RAN's first loss of World War II, and the first RAN surface ship to be lost in wartime. Following the loss of SS Cambridge and MS City of Rayville in November 1940 to sea mines laid off Wilsons Promontory and Cape Otway, Goorangai and two other auxiliary minesweepers, HMA Ships Orara and Durraween, were sent to clear to Bass Strait to sweep for mines.
