Abu Mansur Sabuktigin (ca 942 – August 997), also spelled as Sabuktagin, Sabuktakin, Sebüktegin and Sebük Tigin, also known as Nasir-ud-din Sabuktigin, is regarded as the founder of the Ghaznavid Empire in what is now Afghanistan during the late 10th century.

He lives as a slave during his teens and later marries the daughter of his master Alptigin, the man who seizes the region of Ghazna (modern Ghazni Province in Afghanistan) in a political fallout for the throne of the Samanids of Bukhara.

When his father-in-law Alptigin dies, Sebuktigin becomes the new ruler and expands the kingdom after defeating Jayapala to cover the territory as far as the Neelum River in Kashmir and the Indus River in what is now Pakistan.
