Ashton Charles Agar (born 14 October 1993) is an Australian cricketer who plays domestically for Western Australia and the Perth Scorchers. A left-handed all-rounder, he played two Test matches for the Australian national side during the 2013 Ashes series.
From Melbourne, Agar played underage cricket for Victoria, and represented the Australian national under-19 side in several international games. He left Victoria for Western Australia prior to the 2012–13 season, owing to a lack of opportunity, and made his Sheffield Shield debut in January 2013. The following month, he was called up for Australia's 2012–13 tour of India, where he played a single tour match. Agar toured England and Ireland with Australia A in mid-2013, performing well in the English conditions. Although originally not selected in the touring squad, he made his Test debut for Australia in the first Test of the 2013 Ashes series. Coming in with the score on 117/9, Agar scored 98 runs batting eleventh in Australia's first innings, Agar broke several Test records on debut, including the highest score by a number-11 batsman and the highest partnership for the tenth wicket (with Phillip Hughes – since broken). However, after poor bowling, he was dropped from the team after the second Test of the series.
He made his One Day International debut against England on 8 September 2015. He made his Twenty20 International debut for Australia against South Africa on 6 March 2016.
