Sisir Kumar Mitra (or Shishirkumar Mitra) MBE, FNA, FRS (October 24, 1890 – August 13, 1963) was an Indian Bengali physicist.

Mitra was born and raised in Calcutta. His parents were the doctor Saratkumari and the school teacher Jaykrishna. At the age of nine he witnessed a hot air balloon and became intrigued in the phenomenon, so he began studying science. The family moved to Bhagalpur, where Sisir attended school and the local college. After his father died, his mother supported him through Presidency College of the University of Calcutta where he earned a B.Sc. In 1912 he gained his M.Sc. at the same institution.

Mitra briefly became a scholar performing research before becoming a teacher. Eventually he taught at Bankura Christian College. In 1914 he married Lilavati Devi.

In 1916, Sisir was invited to join the new postgraduate department of physics at the University Science College. He gained a D.Sc. degree in 1919; then he left for Paris, France to study at the University of Paris. There he earned a second D.Sc. and would join Marie Curie at her laboratory. He developed an interest in the new science of radio communication, and went to the University of Nancy to research this field.
