Gedun Drub (1391-1474) (dge 'dun grub) is considered to be the first in the line of reincarnated Dalai Lamas of Tibet. Gedun Drub was a student of Je Tsongkhapa and was recognized as a Dalai Lama after his death.

Gendun Drub was born in a cowshed as the son of nomadic tribespeople, and raised as a shepherd until the age of seven. After this he was placed in Nartang monastery, and by the middle of his life he had become one of the most esteemed scholar-saints in the country.

Some of the most famous texts Gedun Drup wrote were:

• Sunlight on the Path to Freedom, a commentary on Abhidharma-kosha
• Crushing the Forces of Evil to Dust, an epic poem on the life and liberating deeds of Buddha Shakyamuni
• Song of the Eastern Snow Mountain, a poem dedicated to Je Tsongkhapa
