Mary Doreen Cooper-Wright (30 December 1907 – August 2003) was an English swimmer who competed in the 1930 British Empire Games, where she won a gold medal alongside Olive Joynes, Phyllis Harding, and her younger sister Joyce in the 4x100 yard freestyle relay.

Raised in Sri Lanka (then known as Ceylon), Doreen was the oldest of three siblings that included Joyce Cooper,[1] a swimmer who won four medals across two editions of the Olympic Games.

In the latter she competed at the 1930 British Empire Games, where she won a gold medal alongside Joyce, Olive Joynes, and Phyllis Harding in the 4x100 yard freestyle relay.

[citation needed] During the conflict Cooper worked with the Women’s Royal Voluntary Service[1] and, afterwards, served on the county council of Buckinghamshire.

The Leek Wootton History Group received a government grant to publish her diary, which contained a detailed account of local wartime life intermixed with the emotional tale of her lost husband.
