The Shivalik class or Project 17 class is a class of multi-role stealth frigates in service with the Indian Navy. They are the first stealth warships built in India. They were designed to have better stealth features and land-attack capabilities than the preceding Talwar-class frigates. A total of three ships were built between 2000 and 2010, and all three were in commission by 2012.

The Shivalik class, along with the seven Project 17A frigates currently being developed from them, are projected be the principal frigates of the Indian Navy in the first half of the 21st century. Four of the ships of the class were built by Mazagon Dock Limited (MDL) and three by Garden Reach Shipbuilders and Engineers (GRSE), manufacturers of the Mahendragiri. The class and the lead vessel have been named for the Shivalik hills. Subsequent vessels in the class are also named for hill ranges in India.
