Dharma Raja Karthika Thirunal Rama Varma (‘ധര്മ്മ രാജ‘ കാര്ത്തിക തിരുനാള് രാമവര്മ്മ, 1724–17 Feb 1798) was the Maharajah of Travancore from 1758 until his death in 1798. He succeeded his uncle Marthanda Varma, who is credited with the title of "maker of modern Travancore". During his reign Dharma Raja not only retained all the territories his predecessor had gained but administered the kingdom with success. He was addressed as Dharma Raja on account of his strict adherence to Dharma Sastra, the principles of justice by providing asylum to thousands of Hindus and Christians fleeing Malabar during the religious and military onslaught of Tipu Sultan.
