Hayes Common is a 79-Hectare area of public open land in Hayes in the London Borough of Bromley. It is owned and managed by Bromley Council. It is Site of Metropolitan Importance for Nature Conservation, and a small area is part of a Site of Special Scientific Interest. The common is an area of woodland and heath, crossed by bridleways and footpaths. Hayes Common is one of the largest areas of common land in Greater London, with 91.1 hectares (225 acres) of protected commons.
Archaeological excavations have revealed ditches, pits and post holes dating back to the Bronze Age. The name Hayes is recorded from 1177 as hoese from the Anglo-Saxon meaning "a settlement in open land overgrown with shrubs and rough bushes". The common was used for centuries as a place where local people could collect firewood and graze cattle, and by the early nineteenth century it was the site of the Hays Fair, a popular day out for Londoners.
In the 1860s the owner of the land, Sir John Lennard, began to sell off plots in the neighbouring West Wickham Common for housing, and the Hayes commoners feared that their common would suffer the same fate. They organised opposition, and in 1869 Hayes Common was the first common to be protected against enclosure under the Metropolitan Commons Act 1866. In 1937 the Municipal Borough of Bromley became the freeholder of the common, and when the Municipal Borough was abolished in 1965 the London Borough of Bromley inherited ownership. In 2000, the Friends of Hayes Common was formed to help maintain the common.
