In cricket, an umpire is a person who has the authority to make judgements on the field. There are two on-field umpires, who apply the laws, make all necessary decisions, and relay the decisions to the scorers.
The Indian Premier League (IPL) is a professional league for Twenty20 cricket in India, which has been held annually since its first season in 2008. In the eight seasons of the league, 46 umpires have officiated at least one IPL match. Of these, Kumar Dharmasena has officiated the most number of matches, serving as an umpire 74 times, while Subroto Das has officiated the fewest, serving in one match of the 2013 season. The first match of the IPL, played between the Royal Challengers Bangalore and Kolkata Knight Riders, was umpired by Asad Rauf and Rudi Koertzen, while the most recent match, the final of the 2015 season, was umpired by Dharmasena and Richard Illingworth. 21 of the umpires are of Indian nationality, seven are Australians, five are South Africans, four are New Zealanders. Three umpires are from England and two from Pakistan and Sri Lanka each; whereas there is one umpire from West Indies and Zimbabwe each. 13 umpires have served in only one season.
As of the 2013 season, an on-field umpire receives a ₹1.75 lakh (US$2,600) salary for officiating a match. The umpires are sponsored by McDowell's No.1, whose branding is displayed on their uniforms. Kingfisher Airlines were the umpires sponsor for the first five seasons, and they paid ₹106 crore (US$16 million) for the sponsorship. The recipient team of the Fair Play Award is also decided by the number of points given by the umpires in the league. The umpires are also assessed by the umpires' performance and training manager; Taufel was in-charge of that post during the 2013 season.
The list is initially organised by the number of matches as an umpire, and if the numbers are tied, the list is sorted by last name. This list is correct as of the 2015 IPL season, and does not cover the games played by IPL teams in other tournaments or tours, such as the Champions League Twenty20, the British Asian Cup or the 2008 Kolkata Knight Riders tour of Australia.
