RMS Alaunia was an ocean liner built for the Cunard Line during the 1920s which served primarily on the Canadian route.

[1][2] Alaunia was built by John Brown & Company in Scotland to augment the transatlantic passenger fleet of the Cunard Line.

The ship entered service in July 1925 and was primarily employed on the Canadian route running from Southampton to Quebec and Montreal during the warm weather months and Halifax during the winter.

Designed with a single stack and straight stem bow with four passenger decks, the ship was propelled by two screws powered by four double reduction geared steam turbine engines that gave her a service speed of fifteen knots.

Alaunia was sold for scrap to the British Iron & Steel Corporation and subsequently broken up at Blyth, England in 1957.
