Thihathu of Ava (Burmese: သီဟသူ (အင်းဝ), pronounced: [θìha̰ðù]; 1394–1425) was king of Ava from 1422 to 1425. It was during his reign that the Forty Years' War (1385–1424) between Ava and Hanthawaddy Pegu kingdoms came to a formal close. Unlike his late elder brother Minye Kyawswa, he did not consider Pegu his enemy, and followed a policy of conciliation and friendship toward Pegu. In 1423, he actually helped to broker a truce between two rival claimants to the Hanthawaddy throne. For his help in breaking up the fight, Thihathu was given the rival princes' sister Lady Shin Sawbu whom he made his queen.

Though he made peace with Hanthawaddy Pegu in the south, the Shans from various Shan States in the north continued to raid Avan territory. In August 1425, Thihathu was killed in an ambush by the Shan raiders of Thibaw. The ambush was arranged by his queen Shin Bo-Me who wanted to put her lover Kale Kyetaungnyo on the throne.

Thihathu was the second son of Minkhaung, the Prince of Pyinsi by his chief queen Shin Mi-Nauk, a daughter of the saopha (Chief) of the Shan state of Mohnyin. As Minkhaung himself was one-eighth Shan, Thihathu was slightly more Shan (9/16th to be exact) than Burman. During his youth, he grew up in Pyinsi, located about 30 miles south of Ava (Inwa) where his father was in charge. In 1400, he came to Ava when his father ascended the Ava throne. His father made him governor of Sagaing, the city across the river from Ava, in 1408.
