The Brahmaputra-class frigates (Type 16A or Project 16A) are guided-missile frigates of the Indian Navy, designed and built in India. They are an enhancement of the Godavari class, with a displacement of 3850 tons and a length of 126 metres (413 ft). Although of similar hull and dimension, internally, the Brahmaputra and Godavari classes have different configurations, armaments and capabilities. 3 ships of this class serve in the Indian Navy.

The class and the lead ship, INS Brahmaputra, are named after the River Brahmaputra. Subsequent ships of the class, INS Betwa and INS Beas are also named for Indian rivers.
