P. G. N. Unnithan was the last Diwan (Prime Minister) of independent Travancore (Thiruvithamkoor). He succeeded Sir C.P. Ramaswami Iyer on August 20, 1947 following the latter's resignation (subsequent to the attempt on Sir CP's life at the Swathi Thirunal Music academy on July 25, 1947). He chaired the Travancore Constitutional Reforms Committee. He relinquished office on March 24, 1948 when a people's government led by Sri Pattom Thanu Pillai as Prime Minister took over.
Sri PGN Unnithan hailed from the Edassery Pattaveettil Family of Mavelikkara which had a history of high military service to the Travancore Royal Family. His father Ittamar Koil Thampuran was from the Haripad Palace and nephew of Kerala Varma Valiya Koil Thampuran. He married Bhargavi Amma, the daughter of Sri PG Govinda Pillai (Government advocate at Alappuzha) of Pullampilla Pichanattu (Viruthiyathu) Family of Chengannur. His sister was married to the son of famed Artist Raja Ravi Varma of the Royal Family of Mavelikkara. He had four children. He died on April 5, 1965.
Unnithan Lane at Sasthamangalam in Thiruvananthapuram is named after him.
