Dorney Lake (also known as Eton College Rowing Centre, and as Eton Dorney as a 2012 Olympics venue) is a purpose-built rowing lake in England. It is located at grid reference SU929779 near the village of Dorney, Buckinghamshire, and lies near the towns of Windsor and Eton, close to the River Thames. The lake is privately owned and financed by Eton College, which spent £17 million developing it. Additional grants, totalling £500,000, were obtained from Sport England, UK Sport, the DCMS and SEEDA in order to build the lake's finish tower. The project was completed in 2006, after 10 years of construction. Although it is primarily for use by the school, the facilities are hired out for rowing, as well as for canoeing, dragon boating and triathlon training.

The lake will be used as the 2012 Summer Olympic venue for rowing and canoe sprint (the whitewater events will take place at Lee Valley White Water Centre in Hertfordshire), and as the 2012 Summer Paralympic venue for rowing. To provide for Olympic spectators, the existing facilities are being enhanced to include 20,000 additional seats; most of these seats will be temporary. Construction began in October 2009 of enhancements to Dorney Lake, including a new cut-through between the competition lake and the return lane, a new bridge and an upgraded access road, funded by the Olympic Delivery Authority (ODA). During the Olympic events, Dorney Lake will be staffed by around 3,500 personnel, including volunteers.

Dorney is a village and civil parish within South Bucks district in the English county of Buckinghamshire, near Slough and about two and a half miles west of Eton.

The village name is Old English and means "island frequented by bumble bees". This refers to the fact that it was once a patch of hard ground in the middle of a marshy bog, though with modern farming methods the marshland has more or less disappeared. In the Domesday Book of 1086 the village was referred to as Dornei.

The manor house, Dorney Court, is listed among England's many fine country houses. The nearby Dorneywood is used as country home for a senior member of the Government, usually a Secretary of State or Minister of the Crown.

Today the village's proximity to the M4 motorway (therefore with a close link into London) has meant that it is now an area popular with executives and commuters. It is also the location of Dorney Lake, where the canoeing and rowing events at the 2012 Summer Olympics are to be held.
