Rectory Field is a sports ground in Blackheath in the Royal Borough of Greenwich in south-east London. It was developed in the 1880s by Blackheath Cricket, Football and Lawn Tennis Company and became the home ground of rugby union team Blackheath F.C. between 1883 and 2016. The ground has hosted international rugby matches and at one time, along with the Richmond Athletic Ground, it was the unofficial home of the England national rugby union team before the development of Twickenham Stadium. The ground was also used for first-class and List A cricket by Kent County Cricket Club between 1887 and 1972. The field is named after the Charlton Rectory that once stood at the site. It is used today by Blackheath Sports Club for cricket, rugby, tennis and squash.
