Sagina Mahato is a 1970 Bengali film produced by Shri J. K. Kapur and directed by Tapan Sinha.

The film is based on the true story of the labour movement of 1942–43, told through with fictional characters, and the mock trial of Sagina Mahato, the trade union leader of a factory in Siliguri.

This is story of a tea estate labour leader in the north eastern region of India during the British Raj.

Amal, an outsider, turned Sagina as a leader and thus alienated him from the mass by elaborating, appropriating, codifying, approximating his social hierarchy.

The story by Gour Kishor Ghosh (first published in Desh25:12, 18 January 1958, reveals the problems of vulgar vanguardism from the radical humanist standpoint.
