The Talwar-class (lit. 'Sword') frigates or Project 11356 are a class of stealth guided missile frigates designed and built by Russia for the Indian Navy. The Talwar-class guided missile frigates are the improved versions of the Krivak III-class (Project 1135) frigates used by the Russian Coast Guard. The design has been further developed as the Admiral Grigorovich-class frigate for the Russian Navy.

Designed by Severnoye Design Bureau, the first batch of ships were built by Baltic Shipyard and the second and third batch by Yantar Shipyard. Preceded by the Brahmaputra-class frigates, the Talwar-class frigates are said to have semi-stealth features and better armament. The Indian Navy currently operates eight of these ships and two more are under construction at the Goa Shipyard in India.
