SS Commissaire Ramel was a French cargo liner that was launched in 1920 and sunk in the Indian Ocean by the German merchant raider Atlantis in World War II.

The Société Provençale de Construction Navale built the ship in La Ciotat as General Duchesne.

She was powered by a three-cylinder triple expansion engine with coal-fired boilers[2] that delivered 4,450 hp,[clarification needed] driving a single propeller and giving her a speed of 12 kn (22 km/h).

[1] Commissaire Ramel was launched on 20 March 1920, and entered service with the Compagnie des Messageries Maritimes on 24 April 1921, as a cargo liner, sailing between France and the Far East.

Her boilers were converted from coal to oil fuel, and a low-pressure steam turbine was added alongside her triple-expansion engine.

[3] Under the management of the Shaw, Savill & Albion Line she sailed from Sydney on 1 September 1940 bound for Britain via Cape Town,[3] under the command of Captain R MacKenzie.
