SS Redesmere was a small freighter built during the First World War.

The ship was sunk by the German submarine SM U-70 in October 1917.

She had a vertical triple-expansion steam engine driving a single screw propeller.

She was sold to the Lever Brothers' newly formed Bromport Steamship Co. on 11 May 1916.

Redesmere was en route to Southampton from Barry, with a load of coal when she was torpedoed and sunk by UB-40 6 miles (9.7 km) west of St Catherine's Point on 28 October 1917[3] with the loss of 19 crewmen.
