Ali ibn Hasan, also known as Harun Bughra Khan and better known as Ali-Tegin (also spelled Alitigin) was a Karakhanid ruler in Transoxiana from 1020 to 1034 with a brief interruption in 1024/5.

He was the son of Hasan ibn Sulayman Bughra Khan (simply called "Bughra Khan" in Persian sources), who was the eponymous ancestor of eastern branch of the Karakhanid family, known as the "Hasanids", which Ali-Tegin belonged to. Furthermore, Hasan is only known in Persian sources because of his wars with the Iranian Samanids, who used to be the rulers of Transoxiana before the Karakhanids under Nasr Khan annexed their territories in 999.

Ali-Tegin is first mentioned as being thrown in prison under the orders of his opponent Mansur Arslan Khan, but quickly managed to escape and receive help from a group of Oghuz Turks under the Seljuq chief Arslan Isra'il. With these Oghuz Turks under his grasp, Ali-Tegin seized Bukhara and soon occupied all of Sogdia; after his conquest of the region, he took the title of "Yïgan-tigin" and another title of "Arslan Ilig". He then gave his daughter in marriage to Arslan Isra'il. With the possession of the wealthy and important cities of Bukhara and Samarkand, Ali-Tegin became a powerful and influential figure in Central Asia; however, this made his relations with his jealous brother Yusuf Qadir Khan hostile, and resulted in Qadir Khan allying himself with the Ghaznavid Sultan Mahmud, who had received expression of discontent from Ali-Tegin's subjects and was himself annoyed by Ali-Tegin, who did not allow him to send envoys to Qadir Khan, whose territories consisted of the important cities of Khotan and Kashgar. Ali-Tegin, after having received the news of his brother's alliance with the Ghaznavids, responded by allying himself with his other brother Muhammad Toghan Khan.
