Margaret Croft "Peggy" Scriven-Vivian (née Scriven; 17 August 1912 – 25 January 2001) was a British tennis player and the first woman from that country to win the singles title at the French Championships in 1933. She also won the singles title at the 1934 French Championships, defeating Helen Jacobs in the final.
Scriven-Vivian was the last British woman to win the same Grand Slam singles tournament for two consecutive years. In addition, she was the first left-handed woman to win a Grand Slam singles title and up until 2017, the only unseeded woman ever to win the French Championships or French Open.
According to A. Wallis Myers of The Daily Telegraph and the Daily Mail, Scriven-Vivian was ranked in the world top ten from 1933 through 1935, reaching a career high of World No. 5 in those rankings in 1933 and 1934.
