Ravichandran Ashwin () (born 17 September 1986) is an Indian international cricketer from Chennai, who plays for the India cricket team. In Indian domestic cricket he plays for Tamil Nadu and for Rajasthan Royals in the Indian Premier League (IPL). He was part of the Indian team that won the 2011 Cricket World Cup and the 2013 Champions Trophy.

Ashwin is right-arm off-spin bowler. He is fastest Indian bowler (also in some records the joint-fastest in the world) to reach the 50-, 100-, 150-, 200-, 250-, 300-, 350-,400- and 450- wicket mark in Test cricket in terms of number of innings. In 2016, he became the third Indian to win the ICC Cricketer of the Year award. He is currently the highest-ranked bowler in Test cricket, and the highest-ranked bowler ever for India on the ICC Player Rankings. He has won ten Man of the Series awards in Test cricket, which is the highest by an Indian cricketer. He has also scored 5 Test centuries with a highest score of 124. Ashwin with his team won both the 2011 Cricket World Cup, and the 2013 ICC Champions Trophy, where he was the bowler of the final over in which England failed to chase the target.

Having achieved little success as an opening batsman at junior-level cricket, Ashwin dropped down the order and turned into an off-break bowler. He made his first-class debut for Tamil Nadu in December 2006 and captained the team the following season. However, it was not until the 2010 Indian Premier League in which he played for the Chennai Super Kings that he came into the limelight with his economical bowling and earned his maiden international call-up in the limited-overs formats in June 2010. He was the leading wicket-taker and player of the tournament of the 2010 Champions League Twenty20 in South Africa.

He was also part of the Indian squad that won the 2011 Cricket World Cup. Later that year, he made his Test debut against West Indies and became the seventh Indian bowler to take a five-wicket haul on Test debut. He took two five-wicket hauls and scored a century in that series and won the player of the series award.

Ashwin continued to succeed in the subcontinent. In a home Test series against Australia in 2013, he took 29 wickets, the most by any Indian bowler in a four-match Test series. The same year, he took his 100th Test wicket in his 18th match, becoming the fastest Indian bowler to the milestone and the fastest in the world in over 80 years. In 2017, playing his 45th Test, Ashwin became the fastest bowler to pick up 250 Test wickets, bettering Dennis Lillee, who had achieved the landmark in 48 Tests. In October 2019, in his 66th Test match, Ashwin became the joint-fastest bowler, along with Muttiah Muralitharan, to take his 350th Test wicket.

On 10 April 2022, he became the first batsman to officially retire out in an IPL match during a league stage match between Rajasthan Royals and Lucknow Super Giants. He is one of the few players to reach 3000+ runs & 450+ wickets in tests and overall 2nd quickest player to reach this landmark.
