Harisimhadeva (also called Hari Singh Deva) was a King of the Karnat dynasty who ruled the Mithila region of modern-day parts of North Bihar in India and South Nepal.
He reigned from 1304 to 1325. He was the last king of the Karnata dynasty of Mithila. His minister of war and peace was Caṇḍeśvara Ṭhakkura who composed the famous treatise, the Rajanitiratnakara. His reign came to an end after an invasion by Ghiyasuddin Tughlaq forced him to escape in search of sanctuary to the hills of Nepal. His descendants eventually became the founders of the Malla dynasty of Kathmandu who were known for being patrons of the Maithili language.
