Drigum Tsenpo was an emperor of Tibet. According to Tibetan mythology, he was the first king of Tibet to lose his immortality when he angered his stable master, Lo-ngam. Legend states that rulers of Tibet descended from heaven to earth on a cord, and that they were pulled back up when their time came. Lo-gnam cut the cord, leading to Drigum Tsenpo's death; he thus became the first Tibetan ruler to be buried on earth.

There is a detailed, if rather fabulous, account of his life in the Old Tibetan Chronicle.^[1]
