Binnya Waru (Burmese: ဗညားဗရူး, pronounced [bəɲá bəjú]; Mon: ဗညားဗရောဝ်; c. 1418–1451) was the 12th king of the Hanthawaddy Kingdom in Burma from 1446 to 1451. He was a nephew and adopted son of King Binnya Ran I after whom he succeeded to the Hanthawaddy throne. The king was known for his strict disciplinary rule. He reportedly liked to travel around the kingdom disguised as a commoner to observe the affairs firsthand, and meted out justice even to those who committed petty crimes. Binnya Waru was killed by his first cousin Binnya Kyan, son of King Binnya Dhammaraza, in 1451.
