Chalfont Common is a hamlet in the parish of Chalfont St Peter, Buckinghamshire, England. It is located in the Chiltern Hills, approximately one mile to the north east of Chalfont St Peter village centre. Chalfont Common is {{convert|19.7|miles|km}} west-north-west of Charing Cross, central London.

It is located east of the River Misbourne and was one of Chalfont St Peter's three commons (the other two being Gold Hill Common and Austenwood Common). Housing of all sorts developed around and on the common, some dating back to the 1890s.[http://www.francisfrith.com/chalfont-common/chalfont-common-post-office-c1965_c692034 History of Chalfont Common, Francis Frith] In the 1960s a post office was constructed on the common, which has since closed.

It is also the home of the Epilepsy Society which was founded in 1892.
