Binnya U (Mon: ဗညာဥူ, Burmese: ဗညားဦး, Burmese pronunciation: [bəɲá ʔú]; also known as Hsinbyushin; 1323–1384) was king of Martaban–Hanthawaddy from 1348 to 1384. His reign was marked by several internal rebellions and external conflicts. He survived the initial rebellions and an invasion by Lan Na by 1353. But from 1364 onwards, his effective rule covered only the Pegu province, albeit the most strategic and powerful of the kingdom's three provinces. Constantly plagued by poor health, U increasingly relied on his sister Maha Dewi to govern. He formally handed her all his powers in 1383 while facing an open rebellion by his eldest son Binnya Nwe, who succeeded him as King Razadarit.
King Binnya U is best remembered in Burmese history as the father of King Razadarit. One enduring legacy of his reign was Pegu's (Bago's) emergence as the new power center in Lower Burma. The city would remain the capital of the Mon-speaking kingdom until the mid-16th century.
