Moni Guha (29 September 1914, Madaripur ) was an Indian communist. Guha was born to a Bengali lower-middle-class family whose economic circumstances did not allow him to complete his school education.
He joined the struggle for Indian independence, and became an activist of Anushilan Samiti in Faridpur. He was jailed because of his political activities. In prison he met communist leaders, and in the 1940s he became a member of the Communist Party of India. In the latter part of his life, Guha was accorded pension as a freedom fighter.
Guha moved to Calcutta in 1947. He had close contacts with party leaders such as Muzaffar Ahmed and Abdul Halim. He was also active in the Tebhaga movement, and was again imprisoned for a period. After being released from jail he was a trade union organiser amongst factory workers in Calcutta.
