HMCS Orkney was a River-class frigate that served with the Royal Canadian Navy as a convoy escort during the Second World War. She was named for Orkney, Saskatchewan. After the war she was purchased and used by the Israeli immigrant movement, then taken over by the nascent Israeli Navy and renamed Mivtah. She was sold by Israel to Ceylon who renamed her Mahasena.

Orkney was ordered in June 1942 as part of the 1942–1943 River-class program.[3][4] She was laid down on 19 May 1943 by Yarrows Ltd. at Esquimalt and launched 18 September 1943.[4] She was commissioned into the Royal Canadian Navy on 18 April 1944 at Victoria, British Columbia.[3]
