Narahari Tirtha (c. 1243 - c. 1333) was a Dvaita philosopher, scholar, statesman and one of the disciples of Madhvacharya. He is considered to be the progenitor of the Haridasa movement along with Sripadaraja. Though only two of his scholarly works are extant, they are characterised by their verbosity and lack of digressions. A few songs of his survive under the nom de plume Raghukulatilaka.

As a minister of considerable influence to the Eastern Ganga rulers and later as the pontiff of Madhvacharya mutt, Narahari converted the Simhachalam temple into an educational establishment of renown and a religious centre for Vaishnavism.
