Grand vizier (; ; ) was the title of the effective head of government of many sovereign states in the Islamic world. It was first held by officials in the later Abbasid Caliphate. It was then held in the Ottoman Empire, the Mughal Empire, the Sokoto Caliphate, the Safavid Empire and Morocco. In the Ottoman Empire, the grand vizier held the imperial seal and could convene all other viziers to attend to affairs of the state; the viziers in conference were called "Kubbealtı viziers" in reference to their meeting place, the Kubbealtı ('under the dome') in Topkapı Palace. His offices were located at the Sublime Porte. Today, the Prime Minister of Pakistan is referred to in Urdu as Wazir-e-azam, which translates literally to grand vizier.
Initially, the grand viziers were exclusively of Turk origin in the Ottoman Empire. However, after there were troubles between the Turkish grand vizier Çandarlı Halil Pasha the Younger and Sultan Mehmed II (who had him executed), there was a rise of slave administrators (devshirme). These were much easier for the sultans to control, as compared to the free administrators of Turkish aristocratic origin.

The term vizier was originally used in the Abbasid Caliphate in the 8th century AD. This position was later adopted by the Ottomans in the early 14th century, by the Seljuks of Anatolia. During the nascent phases of the Ottoman state, "vizier" was the only title used. The first of these Ottoman viziers who was titled "Grand Vizier" (French spelling: grand-vézir) was Çandarlı Halil Pasha the Elder. The purpose in instituting the title "Grand Vizier" was to distinguish the holder of the sultan's seal from other viziers. The initially more frequently used title of vezir-ı a’zam () was gradually replaced by another one, sadr-ı a’zam ( from Arabic "front part, bosom, forehead, lead, forefront" and "superior, major, maximal, paramount, grand", informally pronounced sadrazam), both meaning "grand vizier" in practice. Throughout the Ottoman history, the Grand Viziers have also been termed sadr-ı âlî (, "sublime vizier"), vekil-ı mutlak (, "absolute attorney"), sâhib-ı devlet (, "holder of the State"), serdar-ı ekrem (, "most noble [commander-in-]chief"), serdar-ı a’zam (, "grand [commander-in-]chief") and zât-ı âsafî (, "vizieral person").
Halil Pasha the Elder reformed the role of the vizier in several ways. Several viziers before him held an equivalent, but differently named office; he was the first who held the position of "Grand Vizier", during the reign of Murad I. He was the first advisor with a military background – his forerunners had come from a more scholarly class of men. It is also significant that he was the first of a political family that, at the time, rivaled the Ottoman dynasty itself. Several of Çandarlı Halil Pasha the Elder's kin went on to hold the office of Grand Vizier in the decades following his death.
Çandarlı Halil Pasha the Younger, the grandson of Pasha the Elder, was also highly influential in shaping the role of the Grand Vizier. During the reign of Mehmed II, the Younger opposed the siege of Constantinople and the ongoing hostilities with Christians. Two days after the siege was won by Mehmed II, the Younger was executed for his opposition. After his death, the position of Grand Vizier was chosen nearly exclusively from the kul system. Often, the men who were chosen had a Byzantine or Balkan background. According to Gábor, this was usually a political move, designed to appease powerful European factions to Ottoman supremacy. In fact, it was easier for the sultan to control an enslaved and non-Turk administrator. In the Ottoman Empire, executing a Grand Vizier of Turkish origin (in the event they were rebellious) and an enslaved foreigner would also give rise to different reactions. Further, the devshirme were less subject to influence from court factions. From the very beginning, the Turcoman were a danger that undermined the Sultan's creation of a strong state.
