Antop Hill is a small hill in Mumbai running north-south to the eastern side of the Harbour Railway line between Wadala & Guru Tegh Bahadur Nagar Stations. It derives its name from a local Marathi owner called Antoba. In course of time the name was anglicised to "Antop". To the south is MBPT (Mumbai Port Trust Colony) and to the north is the C.G.S. colony.
