Khatsun Namkha Lekpa Gyaltsen

Khatsun Namkha Lekpa Gyaltsen (1305–1343) was a Sakya ruler of the Khon family under the Yuan dynasty, holding the seat just as the school's hold on Tibet began to loosen. His father Zangpo Pal, a nephew of Phagpa, had presided over Sakya rule at its height.

After Zangpo Pal died in 1324, the imperial preceptor Kunga Lotro Gyaltsen, Namkha Lekpa's elder brother, divided the brothers among four palace branches, and Namkha Lekpa headed the Zhitog. Made State Preceptor (guoshi) in 1325, he kept the post until 1341.

Under him Sakya failed to put down revolts, and the rival Phagmodrupa gained control of much of the plateau. He died in 1343 and was succeeded by his brother Jamyang Donyo Gyaltsen; his son Kunga Rinchen later became the sixteenth Sakya Trizin.
