Yanda Pyissi (Burmese: ရန္တ ပစ္စည်း, pronounced [ʔjàɴda̰ pjɪʔsí]; also spelled Rantapyissi; c. 1240s – 1284) was a minister in the service of King Narathihapate of the Pagan Dynasty of Burma (Myanmar).
The first mention of Ot-Hla Nge in the Burmese chronicles came in 1258 when he was sent by the young king Narathihapate to the front to Missagiri (in present-day Rakhine State) where the army had been trying to put down a rebellion, with an order to execute Thray Pyissapate, the commander of the operation, for his failure to defeat the rebellion.
Fortunately for Thray Pyissapate, Ot-Hla Nge was intercepted midway by his father, who was on his way back from Martaban (Mottama), having put down a rebellion there.
The campaign ended Missagiri's two-year-old rebellion, and Yazathingyan sent Ot-Hla Nge to Pagan to inform the king of the news of victory.
Starting from 1271, the court faced repeated demands of the Mongol Empire to submit, which the Burmese king rejected.
[5] Yanda Pyissi twice went to the front in northern Pagan territories (present-day Dehong Dai and Jingpo Autonomous Prefecture in Yunnan, and Kachin State) in 1277 and 1283–84.
