Greenwich Peninsula is an area of Greenwich in the Royal Borough of Greenwich bounded on three sides by a loop of the River Thames, between Blackwall and Cubitt Town to the west and Silvertown to the east. To the south is the rest of Greenwich, to the south-east is Charlton.
Formerly known as Greenwich Marshes and as Bugsby's Marshes, it became known as East Greenwich as it developed in the 19th century, but more recently has been called North Greenwich due to the location of North Greenwich Station.
