Serfoji II (Marathi: सर्फोजी, Tamil:‎‎சரபோஜி)(September 24, 1777 – March 7 1832) was the last ruler of the Maratha principality of Tanjore to exercise absolute sovereignty over his dominions. His descendants, however, have managed to thrive as titular Maharajahs of Thanjavur to the present day.

Serfoji belonged to the Bhonsle clan of Marathas, and was descended from Shivaji's half-brother Venkoji. He ruled Thanjavur from 1798, until his death in 1832.
