Ochirtu Setsen Khan (died 1676 or 1677) was a prominent leader of the Khoshut tribe and a ruler of the Four Oirats Confederation. He was the eldest son of Khoshut's Baibaghas Batur Khan and his consort, as well as a nephew of Güshi Khan. From 1637 to 1676, he led the Four Oirats, initially holding the title of Setsen Tayiji (1637–1666). In 1666, he was granted the title of Khan by the Dalai Lama, after which he ruled as Ochirtu Setsen Khan.
