Debendra Mohan Bose (26 November 1885 – 2 June 1975) was an Indian physicist who made contributions in the field of cosmic rays, artificial radioactivity and neutron physics. He was the longest serving Director (1938–1967) of Bose Institute. He served as the President of the Indian Science News Association, and was the editor of its journal Science and Culture for about 25 years. He also served as the treasurer of the Visva-Bharati University.

Bose was the nephew of the famous physicist Jagadish Chandra Bose.

Debendra Mohan Bose was born in Calcutta in a famous Brahmo family. He was the youngest son of Mohini Mohan Bose, one of the first Indians to proceed to U.S.A to qualify himself in homeopathy. Ananda Mohan Bose was his paternal uncle, while Jagadish Chandra Bose was his maternal uncle. After his father's untimely death, Debendra's education was supervised by his uncle J C Bose.

Debendra's plan of getting a degree in engineering from the Bengal Engineering College, Shibpur was cut short when he suffered a severe malaria attack. Nobel laureate Rabindranath Tagore, a close friend of J C Bose, suggested him to pursue physics instead. In 1906, Debendra Bose obtained his MA degree from the University of Calcutta in first class. He worked as a research scholar under J C Bose for one year, during which he participated in his uncle's biophysical and plant physiological investigations.

In 1907, he joined the Christ's College, Cambridge, and worked with prominent physicists including J. J. Thomson and Charles Thomson Rees Wilson at the Cavendish Laboratory. In 1910, he joined the Royal College of Science in London, from where he obtained a diploma and a B.Sc. (first class) in Physics in 1912. Later, he returned to Calcutta and taught physics in the City College, Kolkata in 1913.
