Panchen Sonam Dragpa () (1478–1554) was the fifteenth Ganden Tripa or throneholder of Ganden Monastery. His texts form the core curriculum for the Loseling College of Drepung Monastic University, the Shartse College of the Ganden Monastic University, and several other Gelugpa monasteries. He was taught by the second Dalai Lama, and in turn later became the teacher of the third Dalai Lama.
