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).

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.

In 1931, in the introduction of Mohenjo-daro and the Indus Civilization, London: Arthur Probsthain, 1931, Sir John Marshall wrote, "Three other scholars whose names I cannot pass over in silence, are the late Mr. R. D. Banerji, to whom belongs the credit of having discovered, if not Mohenjo-daro itself, at any rate its high antiquity, and his immediate successors in the task of excavation, Messrs. M.S.

Bandyopadhyay was born on 12 April 1885[1][2] in Berhampore of Murshidabad District, in present-day Indian state of West Bengal, to Matilal and Kalimati.

He won the Jubilee Research Prize of the Calcutta University for The Origin of the Bengali Script published in 1919.

Those discoveries led to excavations at the two sites that established the existence of the then-unknown Bronze Age Indus Valley civilisation.

His other significant non-fiction works include, Prachin Mudra (1915), The Palas of Bengal (1915), The Temple of Siva at Bhumara (1924), The Paleography of Hati Gumpha and Nanaghat Inscriptions (1924), Bas Reliefs of Badami (1928) and The Haihayas of Tripuri and their Monuments (1931).

Having published three novels, Pakshantar (1924), Byatikram (1924) and Anukram (1931), his other literary works in Bengali language were historical fictions.

In 2022, in commemoration of the 137th birth anniversary of the illustrious Rakhaldas Banerji, and to celebrate the centenary year of the discovery of Harappan Civilization, the Indian Museum in Kolkata exhibited some invaluable artefacts from its proud repertoire in order to provide a glimpse of Harappan civilization to the visitors.
