Momo (meaning: crumb) was the 10th Tui Tonga, a dynasty of mighty kings in Tonga, and lived somewhere in the 11th, maybe 12th century AD. He was named after one of the original gods of Tonga, a trio known as Kohai, Koau, mo Momo. It was under his reign that the Tui Tonga maritime empire started to blossom.
