德罗纳（梵文：द्रोण）在摩诃婆罗多中是俱卢族和般度族的上师。德罗纳出生自婆罗门，自幼好学，长大后娶了慈悯大师的妹妹洁里波为妻，两人有一子名马勇，又得到持斧罗摩赐予使用所用武器的神力。后来，德罗纳受持国所聘，教授各王子，德罗纳作为训练，先后派迦尔纳、难敌及阿周那捉拿木柱王，木柱王原是德罗纳年少时的好友，但长大后不屑德罗纳贫穷而断绝来往，最终只有阿周那成功捉到木柱王，德罗纳最后都放走木柱王，但木柱王为此怀仇在心。俱卢大战爆发，德罗纳接替毗湿摩成为俱卢族的主将，而般度族则娶了木柱王的女儿黑公主为妻，与木柱王结为同盟，最终德罗纳被木柱王的儿子猛光所杀。

In the epic Mahabharata, Drona (Sanskrit:द्रोण, বাংলাঃ দ্রোণ, Drona) or Dronacharya (Sanskrit:द्रोणाचार्य, বাংলাঃ দ্রোণাচার্য, Dronacharya) or Gurudrona (Sanskrit-गुरुद्रोण, বাংলাঃ গুরু দ্রোণ,) was the royal preceptor to the Kauravas and Pandavas. He was a descendant of the sage Angirasa. He was a master of advanced military arts, including the divine weapons or Divya Astras. Arjuna was his favorite student. Ashwatthama, another major combatant in the Kurukshetra war, is the son of Drona. Drona is the avatar of Brihaspati.
