Gorampa Sonam Senge (Wylie: go rams pa bsod nams seng ge, 1429–1489) was an important philosopher in the Sakya school of Tibetan Buddhism. He was the author of a vast collection of commentaries on sutra and tantra whose work was influential throughout Tibetan Buddhism. Gorampa is particularly known for his writings on madhyamaka philosophy, especially his critique of the madhyamaka views of Tsongkhapa and Dolpopa. Gorampa defended the mainly anti-realist interpretation of madhyamaka held by the Sakya school (which sees conventional truth as a false illusion).
