Glenn James Maxwell (গ্লেন ম্যাক্সওয়েল) is an Australian professional cricketer. He has played for the Australia national cricket team in all formats of the game since 2012, although he is primarily a One Day International and Twenty20 International specialist. Maxwell is an all-rounder who is known for his sometimes unorthodox batting and bowls right arm off-break deliveries. Domestically he played for Victoria and Melbourne Stars. He was part of the Australian squads that won the 2015 Cricket World Cup, the 2023 Cricket World Cup, and the 2021 T20 World Cup, where in the 2023 final, he scored the winning runs. His ability to make unconventional shots like reverse sweeps and pulls often makes it hard to set fields that cover all of his scoring areas.

Maxwell was born in Kew, Melbourne, and played junior cricket for South Belgrave Cricket Club. He initially played as a fast bowler, before moving to bowl off spin.

Maxwell was selected for Australia's series against Pakistan in the UAE in 2012, with head selector John Inverarity saying that he was "a versatile and lively off-spinning allrounder and brilliant fieldsman" who "will provide another spin bowler option on the slow, low, turning wickets" expected in the country. He made his debut against Afghanistan in the one-off One Day International (ODI) which took place ahead of the matches against Pakistan, before going on to play in five of Australia's six fixtures against the Pakistanis. Scores of 38, 28 and 56 not out in the three ODIs on the tour, saw him selected for two of the three Twenty20 International (T20I) matches, scoring four on T20I debut and 27 from 20 balls in the final match of the tour; he also took his first international wicket.

The same squad of players was selected for the 2012 ICC World Twenty20 in Sri Lanka which followed Australia's matches in the UAE. He played in all five of Australia's group stage matches, taking a single wicket and scoring only eight runs in the two innings in which he batted, but was dropped from the side for the semi-final against West Indies. Following the competition, Maxwell played for Australia A and for the Cricket Australia Chairman's XI against Sri Lanka, Maxwell scored 64 and took 2/70. before being called into the Australian squad for the third Test against the touring Sri Lankans at the end of the year, replacing Shane Watson. He did not play in the Test, but was brought back into the side for three of the five ODIs and both of the T20Is played in January. He was involved in a controversy in the final T20I of the series, after becoming involved in a verbal altercation with opposition players after failing to hit the last ball for four.

Maxwell married his long-time girlfriend Vini Raman in March 2022. The couple have a son born in September 2023. Maxwell is a supporter of the St Kilda Football Club in the Australian Football League.
