(Lochen) Rinchen Zangpo (958–1055), also known as Mahaguru, was a principal lotsawa or translator of Sanskrit Buddhist texts into Tibetan during the second diffusion of Buddhism in Tibet (or the New Translation School or New Mantra School period).
Rinchen Zangpo had been sent as a young man by King Yesh-es-od, who seems to have been ruler of Zanskar, Guge, Spiti and Kinnaur, with other young scholars to Kashmir and other Buddhist centres to study and bring back Buddhist teachings to Western Tibet.
