Tridu Songtsen (Tibetan: ཁྲི་འདུས་སྲོང་བཙན་Wylie: Khri 'dus-srong btsan), Tridu Songtsän or Dusong Mangban, (670–704; r. 676–704 CE) was an emperor of the Tibetan Empire from 676 to 704.

'Dus-rong ascended the Tibetan throne after the death of his father, Mangsong Mangtsen, in 676. The Old Book of Tang says that 'Dus-srong was eight years old in 679 — nine years old by Western reckoning. He was, therefore, presumably born in 670 and was six or seven years old when he began his reign. Due to his youth, he was enthroned with the minister Gar Tongtsen's second son, Khri 'bring, to act as regent.

In 676 the Tibetans made raids on Shanzhou, Guozhou, Hezhou (now Linxia), Diezhou, Migong and Danling in Gansu. The Chinese counterattacked, defeating the Tibetans at Longzhi. The Chinese army led by Li Jingxuan were soundly defeated near Qinghai Lake, however, and by the end of 677 Tibet controlled the whole of the Tarim Basin and the mountainous regions to the southwest.

The western kingdom of Zhangzhung revolted soon after the death of King Mangsong Mangtsen (also known as Trimang Löntsen, Wylie: khri mang slon rtsan, r. 650-677), the son of Songtsän Gampo, but was brought back under Tibetan control by the "firm governance of the great leaders of the Mgar clan" the following year.
