Yazathingyan (Burmese: ရာဇသင်္ကြန်, pronounced: [jàza̰ θɪ́ɴdʑàɴ]; c. 1263 – c. 1312/13) was a co-founder of Myinsaing Kingdom in present-day Central Burma (Myanmar). As a senior commander in the Royal Army of the Pagan Empire, he, along with his two brothers Athinkhaya and Thihathu, led Pagan's successful defense of central Burma against the Mongol invasions in 1287. Following the collapse of the Pagan Empire, the brothers became rivals of King Kyawswa of Pagan in central Burma, and overthrew him in December 1297, nine months after Kyawswa became a Mongol vassal. They successfully defended the second Mongol invasion (1300–01), and emerged the sole rulers of central Burma.

Yazathingyan was born c. 1263 to a prominent family in Myinsaing in Central Burma. His father Theinkha Bo was a younger brother of the sawbwa (chief) of Binnaka, and had fled to Myinsaing after a dispute with his brother in 1260. Traditional (British colonial era) scholarship identifies his father as an ethnic Shan. But the historian Michael Aung-Thwin has rejected the assertion, given that no historical evidence any kind exists to support the claim. At any rate, Theinkha Bo married a daughter of a wealthy banker at Myinsaing. Yazathingyan was the second child of the couple's four children. He had an elder brother Athinkhaya, a younger brother Thihathu, and a younger sister Hla Myat.
