The Queen Elizabeth Oak is a large sessile oak tree (Quercus petraea) in Cowdray Park near the village of Lodsworth in the Western Weald, West Sussex, England.

It lies within the South Downs National Park.

According to this estimate it began to grow in the 11th or 12th century AD.

In June 2002, The Tree Council designated the Queen Elizabeth Oak, one of fifty Great British Trees, in recognition of its place in the national heritage.

[1] According to legend, Queen Elizabeth I stood near the tree with an arrow ready in her bow waiting for a stag to be driven within range for her to shoot it, although she was unsuccessful.
