HMS Coreopsis was a Flower-class corvette, built for the Royal Navy during the Second World War which served in the Battle of the Atlantic.

In 1943, she was transferred to the Royal Hellenic Navy as RHNS Kriezis (Greek: ΒΠ Κριεζής) and participated in the 1944 Invasion of Normandy.

On 20 October 1940, she rescued 33 survivors from the British cargo ship MV La Estancia sunk by the German submarine U-47 south of Iceland.

On 16 November 1942, she rescued 169 survivors from the British merchant ship SS Clan MacTaggart that was sunk by U-92 off Cadiz.
