迦尔纳（梵文：कर्ण）在摩诃婆罗多中是般度族的同母异父兄长。迦尔纳的母亲贡蒂年青时在蔽衣仙人处学会天神降子的神力，于是贡蒂为测试神力向太阳发咒，结果生下了太阳神苏利耶的私生子。

迦尔纳一出生就有神器的盔甲和耳环，但年少的贡蒂不知所惜，便将迦尔纳放在竹篮中随水漂流，最后由一个车伕收养成为养子。迦尔纳长大后武艺高强，在一次王族的擂起比赛中，欲挑战连胜多场的阿周那，但由于迦尔纳是平民，不能参与王族的比赛，不过难敌见到有人可以教训阿周那，即时封迦尔纳为盎迦王，怖军为此出言挑衅迦尔纳，比赛最终只好取消，但已经为迦尔纳和阿周那结下仇怨。比武一事后，迦尔纳和难敌成为挚友，并忠心耿耿为难敌做事。

Karna (Sanskrit: कर्ण, IAST transliteration: Karṇa), originally known as Vasusena, is one of the central characters in the Hindu epic the Mahābhārata, from ancient India. He was the King of Anga (present day Bhagalpur and Munger). Karna was one of the greatest warriors, whose martial exploits are recorded in the Mahābhārata, and the only warrior believed to be able to defeat Arjuna in battle, an admiration expressed by Lord Krishna and Bhishma within the body of this work. As per the Mahabharata, Karna was the only warrior in that era who conquered the entire world. Karna single-handedly successfully conducted Digvijaya Yatra, conquering all kings in every direction of the world in order to establish Duryodhana as the emperor of the world and to conduct the Vaishnava sacrifice. Karna was equal to 2 Maharatha warrior.
