HMS Azalea was a Flower-class corvette that served in the Royal Navy during World War II.

Azalea was laid down by Cook, Welton & Gemmell of Beverley on 15 November 1939; launched on 8 July 1940; and commissioned on 27 January 1941.

On 12 April 1941, Azalea and Kenogami fired a shot over the bow of the U.S.-flagged American Export liner Siboney 320 nautical miles (590 km) out of Lisbon.

After crew aboard Azalea questioned Wenzel Habel, the captain of the unarmed passenger liner, Siboney was allowed to go on her way.

Although Azalea received word via radio of the presence of German torpedo boats from naval headquarters ashore, because of a typographical error in orders, the escorted LSTs did not.
