Rakhal Das Banerji, also Rakhaldas Bandyopadhyay (12 April 1885 – 23 May 1930), was an Indian archaeologist and an officer of the Archeological Survey of India (ASI). In 1919, he became the second ASI officer deputed to survey the site of Mohenjo-daro by Sir John Marshall, director-general of the ASI, and returned there in the 1922-23 season. He was the first person to propose the remote antiquity of the site—which he did in a letter to Marshall in 1923—and in effect of the Harappan culture. After leaving the ASI, he held the Manindra Chandra Nandy professorship of Ancient Indian History and Culture at the Banaras Hindu University from 1928 until his premature death in 1930.
