Uzana I of Pinya (Burmese: ပင်းယ ဥဇနာ, pronounced: [ʔṵzənà]; 1298 – 1356/57) was king of Pinya from 1325 to 1340. Of Pagan royalty, Uzana inherited a disunited kingdom, which fell apart right after his predecessor Thihathu's death. Not only could he not retake the northern Sagaing Kingdom but he also had little control over his southern vassals. Even in his core power base in present-day central Myanmar (Burma), Uzana faced a serious rival in his half-brother Kyawswa. He ultimately lost the power struggle, and abdicated the throne in 1340 to a regent. He lived out his last years as a monk in Mekkhaya.

Born in June 1298, Uzana was the biological child of King Kyawswa of Pagan (r. 1289–97) and Queen Mi Saw U. By his birth, his father had been dethroned for six months, and his mother had been taken by Thihathu, one of the three brothers and former Pagan generals who overthrew Kyawswa. Adopted at birth by Thihathu, co-regent of the newly founded Myinsaing Kingdom, Uzana never knew his biological father who was executed on the orders of the three regents in 1299. The young prince grew up in Pinle with Thihathu's children: his two maternal half-siblings Kyawswa and Nawrahta as well as his step-siblings Tarabya, Saw Yun and Saw Pale.

Perhaps because of his Pagan royal descent, Uzana grew up being a key scion of the Myinsaing ruling house. His stepfather Thihathu, who consolidated power in the following decade, was eager to be seen as a legitimate successor to the Pagan line. On 7 February 1313 at the newly built capital at Pinya, Thihathu proclaimed himself the rightful successor of the Pagan Dynasty, with the dowager queen Pwa Saw of Pagan presenting him the golden belt and the golden tray of the 11th century King Anawrahta. In the same coronation ceremony, he also pronounced Mi Saw U, daughter of King Narathihapate, his chief queen consort, and Uzana his heir-apparent. He also appointed Kyawswa, his eldest son by Mi Saw U, governor of Pinle.
