Hasan b. Sulayman Bughra Khan (Middle Turkic: بغرا خان) was an energetic ruler of western part of Karakhanid state, ruling nominally under Ali Arslan Khan, but de facto independent. He was the grandson of Satuk Bughra Khan through his second son Sulayman Khan. He inherited his father's appanages in the west sometime later before 990, becoming the founder of the Hasanid branch of the Karakhanid family.
