Rush Green is a suburban area in Romford in East London, England.

It is also divided between the Dagenham and Rainham and Romford parliamentary constituencies, each electing a member of parliament.

Other parts extend further south along Dagenham Road into Barking and Dagenham; this neighbourhood is the location of Barking and Dagenham College and Rush Green Library, and was the site of Rush Green Hospital (once the main maternity unit for this part of London), now replaced by a housing estate.

Nearest places are Romford, Dagenham, Elm Park and Becontree Heath.

Since December 2015, Rush Green has been the site of the training ground for West Ham United F.C.
