The Godavari-class frigates (formerly Type 16 or Project 16 frigates) are guided-missile frigates of the Indian Navy. The Godavari class was the first significant indigenous warship design and development initiative of the Indian Navy. Its design is a modification of the Nilgiri class with a focus on indigenous content of 72%, a larger hull and updated armaments.

Two ships of this class currently serve in the Indian Navy. The class and the lead ship, INS Godavari are named after the Godavari River. Subsequent ships in the class, INS Ganga and INS Gomati also take their names from Indian rivers.

INS Gomati was the first Indian Navy vessel to have digital electronics in her combat data system. The ships combine Indian, Russian and Western weapons systems.

The concept for the Godavari class originated from the lessons learnt in the Indo-Pakistan War of 1971. There was a need for a ship unique to Indian requirements, for deploying a hybrid of indigenously-designed, as well as Russian and European weapons systems.

One of the requirements was to deploy two Sea King helicopters from the ship. The Nilgiri-class vessels were too small for this requirement. The final design incorporated a larger hull in order to accommodate this. INS Godavari was decommissioned on 23 December 2015, and her Barak 1 surface-to-air missile will be installed on the flagship INS Vikramaditya.

Although the Directorate of Marine Engineering suggested replacing steam propulsion with gas turbines, it was decided not to do so, since Bharat Heavy Electricals Limited and Hindustan Aeronautics Limited had made heavy investments in facilities and tooling for design of steam turbines and auxiliary systems.
