The Matua Mahasangha (Bengali: মতুয়া মহাসংঘ[1]) is a Hindu reform movement that originated around 1860 AD in modern-day Bangladesh.

The Matua movement originated among the Namasudras, an avarna (outcaste) community of Bengali Hindus, founded by the followers of Harichand Thakur.

The teachings of Harichand, also known as Matuaism, emphasise the importance of education for the upliftment of the population, while also providing a formula for ending social conflict.

[2] Members of the Matua Mahasangha believe in Swayam-Dikshiti ("Self-Realisation") through harinaam, the chanting of the holy name of Hari (God).

According to historian Sekhar Bandyopadhyay, Thakur "experienced atma darshan or self revelation, through which he realized that he was the incarnation of God himself, born in this world to bring salvation to the downtrodden".
