INS Sindhurakshak (Sanskrit, for Protector of the Seas) was a Russian-made Kilo-class 877EKM (Sindhughosh-class) diesel-electric submarine of the Indian Navy. Commissioned on 24 December 1997, it was the ninth of the ten Kilo-class submarines in the Indian Navy. On 4 June 2010, the Indian Defence Ministry and Zvezdochka shipyard signed a contract worth US$80 million to upgrade and overhaul the submarine. After the overhaul, it returned to India from Russia between May and June 2013.

The submarine suffered a minor fire incident in 2010 and a major one on 14 August 2013, which resulted in its sinking at Mumbai's naval dockyard. At the time of its sinking, there were reportedly 18 crew members on board and all of them are either dead or presumed so.

Sindhurakshak was constructed at the Admiralty Shipyard in Saint Petersburg, Russia. Construction of the submarine began in 1995. It was launched in June 1997 and delivered to India in December 1997.

Sindhurakshak was deployed very close to Karachi, Pakistan during the Kargil War in 1999.

On 13 February 2006, during the submarine's deployment in Vishakhapatnam under the Eastern Naval Command, the then President of India A. P. J. Abdul Kalam became the first Indian head of state to sail in a submarine. He was given a demonstrative excursion, during which the submarine dived and sailed in the Bay of Bengal for a few hours. He was accompanied by the Chief of Naval Staff Arun Prakash. The submarine was commanded by Commander P S Bisht.
