Margaret Lennan was a Scottish snooker and billiards player.

Lennan started playing billiards at the age of 17,[1] and received coaching from Alec Donaldson, father of future world snooker champion Walter Donaldson.

[2] in 1928 she won an unofficial "British Isles Championship" by beating Joyce Gardner,[3] and the following year became the first woman to qualify as a billiards coach.

[4][1] The Women's Billiards Association was formed in 1931, and Lennan was one of four professional players appointed to a committee to organise the professional championships, the others being Joyce Gardner, Ruth Harrison and Eva Collins.

[7] Collins was awarded a certificate from the Billiards Association and Control Council for the record break by a woman of 176, made on 3 February 1931[8] and another for her championship record break on 153 in the 1935 Women's Professional Billiards Championship[9] This record was superseded by Ruth Harrison's break of 197 in 1937.
