The Jubilee River is a hydraulic channel in southern England. It is 11.6 km (7.2 mi) long and is on average 45 metres (148 feet) wide. It was constructed in the late 1990s and early 2000s to take overflow from the River Thames and so alleviate flooding to areas in and around the towns of Maidenhead, Windsor, and Eton in the counties of Berkshire and Buckinghamshire.
