Thawun Gyi (Burmese: သဝန်ကြီး, pronounced: [θəwʊ̀ɴ dʑí]; c. 1258 – 1317) was the founder and first ruler of Toungoo (Taungoo), the predecessor state of the Toungoo dynasty of Myanmar. The two-times-great-grandson of King Sithu II founded Toungoo near the end of the Pagan Empire in 1279. He became one of several independent rulers of petty states after the empire's breakup in 1287. He later submitted to Myinsaing, the new power in Upper Burma. Thawun Gyi was assassinated by the men of his younger brother Thawun Nge in 1317.

Thawun Gyi was the elder son of Thawun Letya, the ex-governor of Kanba Myint (ကမ်းပါးမြင့်) and Kya-Khat-Wa-Ya (ကြခတ်ဝရာ) (both in modern Taungoo District). He was born after 1256. According to the regional chronicle Toungoo Yazawin, he was born in Pyu where his father had been placed under house arrest since 1256 by a rival governor from a Mon state to the south, which most likely was Pegu (Bago). The fight between the rival governors took place during a brief interregnum following the death of King Uzana of Pagan (Bagan) c. May 1256. At the capital Pagan (Bagan), a power struggle broke out between Crown Prince Thihathu and his half-brother Narathihapate. The court-backed Narathihapate emerged winner by November 1256. Since Thawun Letya remained under house arrest until his death in 1279, he may have backed Thihathu.
