Dar, who is 43 and from Pakistan, was voted to this award by the 10 Full Member captains as well as the eight-man Emirates Elite Panel of ICC Match Referees, based on his decision statistics and officiating skills over the past 12 months.
It is the third year in a row that he has received the ICC award which was renamed last year after the late England umpire David Shepherd*.
Dar accepted his award from ICC Hall of Fame 2011 inductee Alan Davidson and said: "It's a great honour and I'm thankful to everyone at the ICC and also my colleagues on the Emirates Elite Panel of ICC Umpires along with the Pakistan Cricket Board. I'd like to also thank all my family for all their support since I'm away nearly eight months of the year umpiring."
Dar beat off strong competition from his colleagues on the Emirates Elite Panel of ICC Umpires Steve Davis, Ian Gould and five-time ICC Umpire of the Year Simon Taufel.
Dar, who made his international debut as an umpire in 2000, joined the Emirates Elite Panel in 2004. In the voting period of these awards, Dar stood in five Tests and 13 ODIs. He stood in the ICC Cricket World Cup in the India, Sri Lanka and Bangladesh, where he was an on-field umpire in eight of the matches, including the final between India and Sri Lanka.
Based on the period between 11 August 2010 and 3 August 2011, the LG ICC Awards 2011 ? presented in association with FICA ? take into account performances by players and officials in a remarkable period for the game.
For all the individual awards (with the exceptions of the Women's Cricketer of the Year and the Umpire of the Year), a long-list compiled by the selection panel was forwarded to a 25-person Voting Academy made up of former players, respected members of the media, an elite umpire and an elite match referee. They voted on a three, two, one basis (with three being the highest value) and the winners emerged.
That period includes such high-profile events as the ICC Cricket World Cup 2011 in India, Bangladesh and Sri Lanka, the ICC Intercontinental Cup final, several ICC World Cricket Leagues as well as several bilateral Test and ODI series.
The LG ICC Awards ceremony is now in its eighth year and this year it will be held in London, England. Previous ceremonies were held in London (2004), Sydney (2005), Mumbai (2006), Johannesburg (2007 and 2009), Dubai (2008) and Bengaluru (2010).
