The Tattvasamgraha is a text written by the 8th Century Indian Buddhist pandit Śāntarakṣita. The text belongs to the 'tenets' (Tib. sgrub-mtha) genre and is an encyclopedic survey of Buddhist and non-Buddhist philosophical systems. Śāntarakṣita's student Kamalashila wrote a commentary on it, entitled Tattvasamgrahapanjika.
