Theinkhathu Saw Hnaung (Burmese: သိင်္ခသူ စောနှောင်း, pronounced: [θèiɴgəθù sɔ́ n̥áʊɴ]) was governor of Sagu in the Kingdom of Ava in the late 14th century. He was a grandson of King Thihathu of Pinya, and was one of the four top commanders of King Swa Saw Ke of Ava. He successfully resisted King Thado Minbya's multiple attempts to take his home region (1365−67). He later submitted to Swa. He served in the war against the southern Hanthawaddy Kingdom between 1386 and 1391 and defended the kingdom against the northern state of Mohnyin. Queen Shin Bo-Me of Ava was his granddaughter.
