Avani Sulamani (IAST: Avani-śūlāmani; r. c. 620-645 CE) was an Indian king from the Pandyan dynasty. He ruled parts of the present-day Kerala and Tamil Nadu. He bore the title Maravarman, which was also assumed by the later Pandyan rulers. K. A. Nilakanta Sastri dates his reign to c. 620-645 CE; T. V. Sadasiva Pandarathar dates it to c. 600-625 CE.
Avani Sulamani was the son of Kadungon, who revived the Pandyan rule after the Kalabhra interregnum. Not much information is available about either of these kings. A Pandyan inscrpition praises Avani Sulamani using conventional phrases, claiming that he became the sole owner of the earth and married the goddess of prosperity.
He was succeeded by his son Jayantavarman.
