Baysunghur was the ruler of the Aq Qoyunlu from 1490 to 1493. He was the son and successor of Ya'qub Beg (r. 1478–1490). He had little power during his short reign, serving as a figurehead, while real power was in possession of his tutor and commander Sufi Khalil Beg Mawsilu in 1490–1492, and then under another commander, Sulayman Beg Bijan in 1492–1493. Baysunghur was killed in 1493 by his cousin Rustam Beg, who succeeded him.
