Mitchell Aaron Starc (মিচেল স্টার্ক) is an Australian international cricketer who plays for the Australian national team and New South Wales in domestic cricket. A left-arm fast bowler and a lower order left-handed batsman, he is Australia's fourth highest wicket-taker in both Test and One Day International (ODI) cricket.

Starc began playing international cricket in 2010, but the early part of his career was disrupted by persistent injuries. He came to worldwide attention as a prominent member of the Australian squad that won the 2015 Cricket World Cup, and was declared Player of the Tournament as a result of his consistent performances throughout the matches. He also was a part of the team that won the 2023 ICC Cricket World Cup. At the 2019 Cricket World Cup, he picked up 27 wickets, which is an all-time record for the most wickets taken in a single edition of the tournament. In doing so, he became the leading wicket-taker in successive Cricket World Cup tournaments, having previously achieved the feat in 2015 as well. As of November 2023, he is the 3rd-highest wicket taker of all time in ICC Cricket World Cups.

Starc started playing cricket from a young age, at 9 years old for Northern Districts as a wicket keeper. He was a representative cricketer of the Northern Districts Cricket Association and attended Homebush Boys High School, representing the school's 1st grade cricket team. He is also a former junior cricketer for the Berala Sports Cricket Club in Sydney, where he was known to wicket keep and bowl in the same innings.

Starc had a rookie contract with New South Wales for the 2008/09 summer, and in February 2009 was brought into their squad to replace Aaron Bird after Bird was suspended for having an illegal bowling action. He made his first-class debut in New South Wales' final match of the season on 5 March 2009 against Western Australia. The match was drawn and New South Wales finished on the bottom of the ladder for the 2008–09 Sheffield Shield season as a result.

Starc is of Slovene descent. He is the elder brother of Australian Olympic high jumper Brandon Starc.

In 2015, Starc became engaged to fellow Australian cricketer Alyssa Healy, and they married on 15 April 2016. Starc and Healy were only the third married couple to both play Test cricket, after Roger and Ruth Prideaux, who represented England in the 1950s and 1960s, as well as Guy and Rasanjali de Alwis, who represented Sri Lanka in the 1980s and 1990s. They have since been joined by married women's couples: Katherine and Nat Sciver-Brunt, and Marizanne Kapp and Dane van Niekerk. They met when they were 9, when both were wicketkeepers for Northern Districts. In March 2020, Starc flew home ahead of the final ODI match against South Africa so he could watch Healy play in the final of the 2020 ICC Women's T20 World Cup.

Starc supports the Greater Western Sydney Giants in the Australian Football League. He and his wife Alyssa Healy were named joint number 1 ticket holders of the club in 2025. He also grew up supporting rugby league club the St. George Dragons.
