RFA Dewdale (A151) was a Dale-class fleet tanker and landing ship (gantry) of the Royal Fleet Auxiliary.

Taken over by the Admiralty and completed as a Landing Ship Gantry carrying 15 LCMs with accommodation for 150 military personnel.

Credited with shooting down two Ju 88s at Bougie, she was later damaged by bombing at Algiers and returned to UK for repairs in October 1944.

Reconverted to a tanker at Portsmouth by March 1947, she resumed freighting duties before being sold to Netransmar Cie. SA for scrap in 1959.
