Arab Muslims (Arabic: ) are adherents of Islam who identify linguistically, culturally, and genealogically as Arabs. Arab Muslims greatly outnumber other ethnoreligious groups in the Middle East. Arab Muslims comprise a majority of the population in Algeria, Bahrain, Egypt, Iraq, Jordan, the Palestinian territories, Oman, Qatar, Saudi Arabia, Syria, the United Arab Emirates, Tunisia, and Yemen. Libya, Tunisia, Algeria and Morocco are mistakenly considered Arab-only countries, whereas they also contain Amazigh, natives of those countries.  Not all citizens of Arab-Muslim majority countries identify as Arab Muslims; many Arabs are non-Muslim and many Muslims are of non-Arab ethnicity. Arab Muslims form the largest ethnic group among Muslims in the world, followed by Bengalis, Punjabis, and Javanese.
Some citizens of Egypt and Lebanon identify as Egyptian and Lebanese more so than they identify as Arab or Muslim.
A substantial number of Arab Muslims live in the Arab diaspora. Arab Muslims comprise the majority of the Arab populations in Belgium, France, Germany, Indonesia, Iran, Israel, the Netherlands, Turkey, and the United Kingdom, while Arab Christians are the majority of the Arab populations in Argentina, Australia, Brazil, Chile, Colombia, Cuba, Greece, Haiti, Mexico, the United States, Uruguay, and Venezuela. Around a quarter of Arab Americans identify as Arab Muslims.
