Mahendra Singh Dhoni (commonly known as M. S. Dhoni; born 7 July 1981) is an Indian cricketer and the current captain of the Indian national cricket team in limited-overs formats. An attacking right-handed middle-order batsman and wicket-keeper, he is widely regarded as one of the greatest finishers in limited-overs cricket.He made his One Day International (ODI) debut in December 2004 against Bangladesh, and played his first Test a year later against Sri Lanka.

Dhoni holds numerous captaincy records such as most wins by an Indian captain in Tests and ODIs, and most back-to-back wins by an Indian captain in ODIs. He took over the ODI captaincy from Rahul Dravid in 2007 and led the team to its first-ever bilateral ODI series wins in Sri Lanka and New Zealand. Under his captaincy, India won the 2007 ICC World Twenty20, the CB Series of 2007–08, the 2010 Asia Cup, the 2011 ICC Cricket World Cup and the 2013 ICC Champions Trophy. In the final of the 2011 World Cup, Dhoni scored 91 not out off 79 balls to take India to victory for which he was awarded the Man of the Match. In June 2013, when India defeated England in the final of the Champions Trophy in England, Dhoni became the first captain to win all three ICC limited-overs trophies (World Cup, Champions Trophy and the World Twenty20). After taking up the Test captaincy in 2008, he led the team to series wins in New Zealand and West Indies, and the Border-Gavaskar Trophy in 2008, 2010 and 2013. In 2009, Dhoni also led the Indian team to number one position for the first time in the ICC Test rankings. In 2013, under his captaincy, India became the first team in more than 40 years to whitewash Australia in a Test series. In the Indian Premier League, he captained the Chennai Super Kings to victory at the 2010 and 2011 seasons, along with wins in the 2010 and 2014 editions of Champions League Twenty20. He announced his retirement from Tests on 30 December 2014.
