Emma Liddell (born 30 March 1980) is an Australian former cricketer.^[1]

Liddell played 80 Women's National Cricket League matches for the New South Wales Breakers.^[2] She also played three Tests and 33 One Day Internationals for the Australia national women's cricket team.^[1] She was the 141st woman to play Test cricket for Australia,^[3] and the 95th woman to play One Day International cricket for Australia.^[4]

Liddell attended Grantham High School, in Sydney's western suburbs. She took up playing cricket at the age of 14, following her brother into the sport.^[5] In February 1996, aged 15, she turned out for a representative Metropolitan West side at the annual New South Wales Combined High Schools Cricket Championships, held in Penrith. On the first day of the tournament, in a match against Metropolitan East, she dismissed the entire opposing side without conceding a run, finishing with figures of 10/0 from 7.4 overs.^[6][7] All her victims were clean-bowled,^[8] with the team as a whole scoring only seven runs.^[5] The feat is one of the rarest in cricket – only 24 instances have been recorded across all levels of the game, with Liddell the only woman known to have completed it.^[9]
