The Bijon Setu massacre (Bengali: বিজন সেতু হত্যাকাণ্ড), or Ananda Margi Monks killing, was the killing and burning of 16 sadhus and a sadhvi belonging to Ananda Marga at Bijon Setu, near Ballygunge, Kolkata in West Bengal, India, on 30 April 1982. Despite the attacks being carried out in broad daylight, no arrests were ever made. After repeated calls for a formal judicial investigation, a single-member judicial commission was set up to investigate the killings in 2012.
