Uṣṇīṣavijayā ("VictoriousOne with Ushnisha"; Tibetan: གཙུག་གཏོར་རྣམ་རྒྱལ་མ།, Wylie: gtsug tor-rnam-rgyal-ma, THL: Tsuktor Namgyelma; Mongolian: Бизьяа,Намжилмаа, Жүгдэрнамжилмаа, "Crested Ultimate Tara"; Chinese: 佛頂尊勝佛母)is a buddha of longevity in Buddhism.

If an individual who is suffering from a heavy disease that doctors cannot diagnose does the practice that Gautama Buddha taught to the deva Denpa, she or he will be completely liberated from that suffering, bring to an end all future rebirths in the lower realms, and after death is reborn in a blissful pure land. For humans, the current life will be their last rebirth from the womb.
