Arab tribes are prevalent in the Arabian Peninsula, Mesopotamia, Levant, Egypt, Maghreb, the Sudan region and Horn Africa.

The Arabs of the Levant are traditionally divided into Qays and Yaman tribes. The distinction between Qays and Yaman dates back to the pre-Islamic era and was based on tribal affiliations and geographic locations.; they include Banu Kalb, Kinda, Ghassanids, and Lakhmids. The Qays were made up of tribes such as Banu Kilab, Banu Tayy, Banu Hanifa, and Banu Tamim, among others. The Yaman, on the other hand, were composed of tribes such as Banu Hashim, Banu Makhzum, Banu Umayya, and Banu Zuhra, among others.

There are also many Arab tribes indigenous to Mesopotamia (Iraq) and Iran, including from well before the Arab conquest of Persia in 633 CE. The largest group of Iranian Arabs are the Ahwazi Arabs, including Banu Ka'b, Bani Turuf and the Musha'sha'iyyah sect. Smaller groups are the Khamseh nomads in Fars Province and the Arabs in Khorasan.As a result of the centuries-long Arab migration to the Maghreb, various Arab tribes (including Banu Hilal, Banu Sulaym and Maqil) also settled in the Maghreb and formed the sub-tribes which exist to present-day. The Banu Hilal spent almost a century in Egypt before moving to Libya, Tunisia and Algeria, and another century later moved to Morocco.

According to Arab traditions, tribes are divided into different divisions called Arab skulls, which are described in the traditional custom of strength, abundance, victory, and honor. A number of them branched out, which later became independent tribes (sub-tribes). The majority of Arab tribes are descended from these major tribes.
