Byattaba (Burmese: ဗြတ်ထဗ; Burmese pronunciation: [bjaʔ tʰə ba̰]; also Byat-Hta-Ba) was the ruler of the Martaban province of the Martaban–Hanthawaddy Kingdom from 1364 to 1388. He came to power by staging a coup against King Binnya U with the help of his brothers. Their rebellion led to the relocation of the Mon-speaking kingdom's capital to Pegu (Bago) in 1369.
