The Quraysh or Quraish (Arabic: قريش‎, Qurayš; other transliterations include "Quresh", "Qurrish", "Qurish", "Qirsh", "Qureshi", "Kuraish", "Koraish", "Koreish" and "Coreish") were a powerful merchant tribe that controlled Mecca and its Kaaba upon the appearance of the religion of Islam.

Muhammad was born into the Banu Hashim clan of the Quraysh tribe.

According to Arabic history books, the Quraysh were a branch of the Banu Kinanah tribe, which descended from the Khuzaimah. For several generations they were spread about among other tribal groupings. About five generations before Muhammad the situation was changed by Qusai ibn Kilab. By war and diplomacy he assembled an alliance that delivered to him the keys of the Kaaba, an important pagan shrine which brought revenues to Mecca because of the multitude of pilgrims that it attracted. He then gathered his fellow tribesmen to settle at Mecca, where he enjoyed such adulation from his kin that they adjudged him their de facto king, a position that was enjoyed by no other descendant of his. Different responsibilities were apportioned between different clans. There were some rivalries among the clans, and these became especially pronounced during Muhammad's lifetime.
