Nāropā or Abhayakirti was an Indian Buddhist Mahasiddha. He was the disciple of Tilopa and brother, or some sources say partner and pupil, of Niguma. As an Indian Mahasiddha, Naropa's instructions inform Vajrayana, particularly his six yogas of Naropa relevant to the completion stage of anuttarayogatantra.
He was also one of the gatekeepers of Vikramashila monastery which is located in Bihar.
Although some accounts relate that Naropa was the personal teacher of Marpa Lotsawa, other accounts suggest that Marpa held Naropa's lineage through intermediary disciples only.
