Doris (P84) was a British-built V-class submarine loaned to the Free French Naval Forces in 1944 during World War II.

[1][2] The Royal Navy decided to loan Vineyard to the Free French Naval Forces, who initially planned to rename her Laubeuf, then considered Joule before settling on the name Doris.

[1] On either 30 June[1] or 1 August 1944,[2] according to different sources, the Royal Navy transferred the submarine to the Free French Naval Forces.

[1][2] After training and testing on the River Clyde in Scotland, Doris departed the United Kingdom for Oran in French Algeria on 4 October 1944.

[1][2] She made stopovers at the submarine bases at Lorient and Brest, France, before her arrival in the United Kingdom.
