Yusuf Has Hacib) was an 11th century Uyghur scribe from the city of Balasaghun, the capital of the Karakhanid Empire. He wrote the Kutadgu Bilig and most of what is known about him comes from his own writings in this work.

Balasagun was located near present-day Tokmok in Kyrgyzstan. Yusuf Has Hajib was about 50 years old when he completed the Kutadgu Bilig. After presenting the completed work to the prince of Kashgar he was awarded the title "Khāṣṣ Ḥājib", an honorific similar to "Privy Chamberlain" or "Chancellor".

He is often referred to as either Yūsuf Balasaguni or unicode|Yūsuf Khāṣṣ Ḥājib.

Some scholars suspect that the prologue to the Kutadgu Bilig, which is much more overtly Islamic than the rest of the text, was not written by Yūsuf, particularly the first prologue, which is in prose, unlike the rest of the text.Yusuf Has Hajib died in 1085 at the age of 66 in uyghur city Kashgar, and was buried there. There is now a mausoleum erected on his gravesite . He is remembered as a prominent Uyghur scholar
