Empress Khri ma lod (or Thrimalö) was an unofficial co-ruler of the Tibetan empire, 675-689 and 704-712 CE. Her title was tsenmo (the female equialent of tsenpo, the Tibetan title most frequently translated as emperor).

Khri ma lod was married to emperor Mangsong Mangtsen (Trimang Löntsen' or Khri-mang-slon-rtsan). The emperor died in the winter of 676-677, and in the same year she gave birth to the emperor's son Tridu Songtsen (Khri 'dus-srong btsan or Khri-'dus-srong-rtsan).

The Zhangzhung revolted early in her son's reign. She shared power with the Gar (Mgar) clan. When her son Tridu campaigned in the northeast 700-4 CE, she resumed her administrative regency at home.

Khri ma lod gave birth to Gyältsugru (Rgyal-gtsug-ru) in 704. Upon the death of Tridu Songtsen that year, Khri ma lod ruled as regent again for his half-brother. The following year the elder son of Tridu Songtsen, Lha Balpo (Lha Bal-pho) apparently contested the succession of his one-year-old brother, but was "deposed from the throne" at Pong Lag-rang.

Khri ma lod had arranged for a royal marriage of Gyältsugru to a Chinese princess. The Princess Jincheng (金成) (Tibetan: Kyimshang Kongjo) arrived in 710, but it is somewhat unclear whether she married the seven-year-old Gyältsugru or the deposed Lha Balpo.

Khri ma lod died in 712. Gyältsugru was then officially enthroned with the royal name Tride Tsuktsän. Khri ma lod remains the only woman in Tibetan history to rule Tibet.
