Virginia Water Lake lies on the southern edge of Windsor Great Park, in the borough of Runnymede in Surrey and the civil parishes of Old Windsor and Sunningdale in Berkshire, in England. It is a man-made lake taking its name from a natural body of water of the same name. There is a village of Virginia Water which stretches out to the east of the lake. The grounds of the lake, nearby Fort Belvedere, and the Clockcase are all Grade I listed on the Register of Historic Parks and Gardens.

Windsor Great Park is a Royal Park of 2,020 hectares, including a deer park, to the south of the town of Windsor on the border of Berkshire and Surrey in England. It is adjacent to the private 265 hectares Home Park, which is nearer the castle. The park was, for many centuries, the private hunting ground of Windsor Castle and dates primarily from the mid-13th century. Historically the park covered an area many times the current size known as Windsor Forest, Windsor Royal Park or its current name. The park is managed and funded by the Crown Estate, and is the only royal park not managed by The Royal Parks. Most parts of the park are open to the public, free of charge, from dawn to dusk, although there is a charge to enter Savill Garden.
