INS Vindhyagiri (F42) was a Nilgiri-class frigate of the Indian Navy. Vindhyagiri was commissioned on 8 July 1981, but capsized after colliding with a merchant vessel on 30 January 2011. It was subsequently salvaged and then decommissioned on June 11, 2012. It served for 31 years in the navy and in its prime served as the flagship of the Western Naval Command. It was decommissioned a year earlier than envisaged due to the collision.
