Blackfen School for Girls is a girls' secondary school and sixth form with academy status, located in Blackfen in the London Borough of Bexley, England. Although it is a girls school, the sixth form over the past few years has become mixed. This is due to the partner school Hurstmere Foundation School having no sixth form, so many pupils from Hurstmere join the sixth form in Blackfen school. The headmaster is currently Matthew Brown, having previously been Louise Sharples.
