SS Primrose Hill was a British CAM ship that saw action in World War II, armed with a catapult on her bow to launch a Hawker Sea Hurricane. She was completed by William Hamilton & Co in Port Glasgow on the Firth of Clyde in September 1941. Primrose Hill was managed by Counties Ship Management Ltd of London (CSM), an offshoot of the Rethymnis & Kulukundis shipbroking company. Primrose Hill was CSM's second CAM ship, in effect replacing Michael E that had been torpedoed and sunk three months previously on her maiden voyage.
