Ngawang Khedrub (Mongolian: Agvangqayidub) was a Khalkha Mongolian scholar who studied at Ganden Shedrubling of Ikh Khuree in Mongolia, and later at Drepung Monastery in Lhasa. Returning to Mongolia, he served as a choje and the vice abbot, and also as the abbot of Ikh Khuree. He contributed significantly to the development of Ikh Khuree, which would become the most influential monastic center in Mongolia. He trained a substantial number of disciples and wrote extensively, with five volumes comprising his collected works. When the Fourth Jebtsundamba unexpectedly died during a trip to Wutai Shan, Ngawang Khedrub is said to have acted as an interim representative until the Fifth Jebtsundamba was discovered. In addition to his writings, which covered poetry, prayers and supplications, fables, commentarial exegeses of Buddhist philosophy and tantra, polemics, biographies, catalogs, rituals, and practical advice, Ngawang Khedrub either himself created or at least commissioned several portraits of the Second Reting, and was responsible for the creation of numerous statues of buddhas, bodhisattvas, and the Fourth Jebtsundampa.
