The 2011 Aegon Championships (also known traditionally as the Queen's Club Championships) was a men's tennis tournament played on outdoor grass courts. It was the 109th edition of the Aegon Championships and was part of the ATP World Tour 250 series of the 2011 ATP World Tour. It took place at the Queen's Club in London, United Kingdom, in the club's 125th year. The tournament was scheduled to take place between 6 and 12 June 2011, however the finals were delayed to 13 June 2011 due to rain.[3] The field was headlined by the 2008 champion and current world number one Rafael Nadal, four-time champion Andy Roddick, 2009 champion Andy Murray and defending champion Sam Querrey.
In the singles competition, the defending champion Sam Querrey lost in round three, paving the way for Andy Murray to win his second title; Murray became the first Briton since Gordan Lowe to win multiple Queen's titles.[4] While in the doubles the defending champion was absent, Bob and Mike Bryan won their 4th Aegon doubles title, their first since 2005.
