Unmiashtart was a Phoenician Queen of Sidon. She ruled Sidon in the late 6th century BC, likely as the regent of her son during his minority.

Unmiashtart was married to King Bodashtart (525-515 BC). She was the mother of King Yatonmilk (515-486 BC).

There were few women in preserved documentation confirmed to have ruled a Phoenician city state, but Unmiashtart are known to have ruled Sidon during the early reign of her son as Co-Regent, likely as Regent during the minority of her son.
