The Purbo Banglar Communist Party is an outlawed communist party and militant far-left organization in Bangladesh. The PBCP formed in 1968 following a split in the Bangladesh Communist Party. It is mainly active in the areas of Khulna and Jessore in the south west of Bangladesh near the border of the Indian state of West Bengal where CPI-Maoist Naxalite insurgents have been active in an ongoing civil war against the Indian state. The PBCP suffers from violent rivalry both internally and externally with different party factions and rival splinter groups. The PBCP was criticized in 1972 by Siraj Sikder, the founder of the Purbo Bangla Sarbohara Party, as being neo-revisionist and a party that is "left in form but right in essence".
