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.

North Greenwich is a formal 19th century name for an area now in Millwall situated at the very southern tip of the Isle of Dogs, in the London Borough of Tower Hamlets. It lies to the south of the commercial estates of West India Docks including Canary Wharf and has a short shoreline along London's Tideway part of the River Thames.
