North Greenwich is a London Underground station. Despite its name, it is not in the local area historically known as North Greenwich, on the Isle of Dogs, north of the River Thames; a completely different North Greenwich station used to be there, from 1872 until 1926. It is actually closer to Charlton than to Greenwich; however, it is at the northernmost tip of the Royal Borough of Greenwich, which perhaps gives the best explanation of the name.

Charlton is an area of southeast London, England, in the Royal Borough of Greenwich. It is east of Greenwich and west of Woolwich, on the south bank of the River Thames, 7.2 miles (11.6 km) southeast of Charing Cross. An ancient parish in the county of Kent, it became part of the metropolitan area of London in 1855 and is home to Charlton Athletic F.C. and Charlton House.
