Archaeological excavations have revealed pieces from the late-Neolithic period and 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.
The common has also been the venue for the crowning of the London May Queen for 105 years as of 2017.

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.

During the Second World War there were eight anti-aircraft guns fitted there, four 4.5 guns on permanent bases and four mobile 3.7 guns
