INS Betwa (F39) is a Brahmaputra-class guided missile frigate currently in service with the Indian Navy. The ship is named for the Betwa River.

Betwa was a part of Task Force 54, returning from the Mediterranean, when the 2006 Israel-Lebanon Conflict broke out. As a part of Operation Sukoon, Betwa participated in the evacuation of Indian citizens from Lebanon to Cyprus.

On 4 January 2014, the ship hit an unidentified object underwater and cracked the sonar dome, and had also seen salt water ingress into sensitive equipment.

On 5 December 2016, Betwa slipped off support blocks and over onto its port side when refloating and undocking inside the cruiser graving dock at the Naval Dockyard in Mumbai during refit repairs, killing 2 sailors and injuring 15 others. The ship's main mast was also damaged.

Sources initially reported that the salvage and repair of the ship would take approximately two years. Resolve Marine Engineering, a US-based firm, was contracted to salvage the flooded vessel in January 2017 for a sum of Rs. 20 Crore (20 million Indian Rupees, approximately USD $300,000 at the time).

On 22 February 2017, it was reported that the ship was made upright and refloated.Betwa was restored to an upright position by the US salvage company by systematically flooding and pumping her compartments. The US company rolled the vessel upright inside the dry dock without using any external lifting mechanisms. The plan is to refit and make the ship operational by April 2018.
