Bhavabhushan Mitra, or Bhaba Bhusan Mitter, alias Swami Satyananda Puri was a Bengali Indian freedom fighter and an influential social worker.

Jugantar or Yugantar was one of the two main secret revolutionary trends operating in Bengal for Indian independence. This association, like Anushilan Samiti, started in the guise of a suburban health and fitness club while secretly nurturing revolutionaries. Several Jugantar members were arrested, hanged, or deported for life to the Cellular Jail in Andaman and many of them joined the Communist Consolidation in the Cellular Jail.
