Dinendranath Tagore (16 December 1882– 21 July 1935), also known as Dinu Thakur, was a Bengali musician, singer and poet.

He was particularly well-trained in Hindustani classical music, and many early Rabindra Sangeet renderings in his baritone voice can be found in archives and recordings.

Perhaps for this reason, he was affectionately and respectfully called "Amar gaaner bhandari" [the keeper of my songs] by Rabindranath himself.

Dinendranath could play a number of Eastern and Western musical instruments also, notable being the esraj and piano.

He was also involved with a number of dance dramas of Tagore, including a tour performing Taser Desh (Land of cards) to Bombay in 1933.
