Mark Weston (born Mary Louise Edith Weston, 30 March 1905 – 29 January 1978), nicknamed "the Devonshire Wonder", was one of the best British field athletes of the 1920s. He was a national champion in the women's javelin throw and discus throw in 1929 and won the women's shot put title in 1925, 1928 and 1929. At the 1926 Women's World Games he finished sixth in the two-handed shot put, where the final result was a sum of two best throws with the right hand and with the left hand.
