Baranagar Math or Ramakrishna Math, Baranagar was the first monastery of Ramakrishna Order. In September 1886, after the death of Ramakrishna, when his devotees stopped funding, Swami Vivekananda and other disciples of Ramakrishna decided to make a dilapidated house at Baranagar their new math. The house crumbled to dust in 1897. In 1973 Vivekananda Math Samrakshan Samity was formed who attempted to preserve the area. In 2001, the possession was handed over to Belur Math authority, who soon-after declared it as one of their official branch. The restoration and development work of the area is still going on.

Ramakrishna, also called Ramakrishna Paramahansa, born Gadadhar Chattopadhay, was an Indian Hindu mystic. A devotee of the goddess Kali, Ramakrishna after adhering to various religious practices from the Hindu traditions of Vaishnavism, Tantric Shaktism, and Advaita Vedanta, as well as from Islam and Christianity, proclaimed that various world religions are "so many paths to reach one and the same goal", thus validating the essential unity of religions. His parable-based teachings espoused the ultimate unity of diverse religions as being means to enable the realization of the same God. He is regarded by his followers as an avatar or divine incarnation of God.
