is a 3.6-kilometre-long Promenade along the Netaji Subhash Chandra Bose Road
in South Mumbai in the city of Mumbai, India. Often, the names Marine Drive and Netaji Subhash Chandra Bose Road are used interchangeably to refer to this 3.9km stretch. The road and promenade were constructed by late philanthropist Bhagojisheth Keer and Pallonji Mistry. It is a 'C'-shaped six-lane concrete road along the coast of a natural bay. At the northern end of Marine Drive is Girgaon Chowpatty and the adjacent road along links Nariman Point at southern tip to Babulnath and Malabar Hill at northern tip. Marine Drive is situated on reclaimed land facing west-south-west. Marine Drive is also known as the Queen's Necklace
because, when viewed at night from an elevated point anywhere along the drive, the street lights resemble a string of pearls in a necklace.
