Ali (Arabic: علي‎, ʿAlī) is a male Arabic name, derived from the Arabic root ʿ-L-Y which literally means "high". It is a common name in Arabic countries and the rest of the Muslim world.

Islamic traditional use of the name goes back to Ali ibn Abu Talib, the Islamic leader and cousin of Muhammad, but the name is identical in form and meaning to the Hebrew: עֵלִי ‎, Eli, which goes back to the Eli in the Books of Samuel.

The name Ali can arise away from Islam; among English-speakers as short for male and female names starting with "Al-", or the Old Norse man's name Áli.

Ali is also a Finnish male given name, derived from Aleksanteri.

Alī ibn Abī Ṭālib (Arabic: علي بن أﺑﻲ طالب, Transliteration: ʿAlī ibn Abī Ṭālib, [ʕaliː ibn ʔæbiː t̪ˤɑːlib]; 13^thRajab, 24 BH–21^stRamaḍān, 40 AH; approximately October 23, 598 or 600 or March 17, 599 – January 27, 661). The son of Abu Talib, Ali was also the cousin and son-in-law of Islamic prophet Muhammad, ruling over the Islamic Caliphate from 656 to 661, and was the first male convert to Islam.Sunnis consider Ali the fourth and final of the Rashidun (rightly guided Caliphs), while Shias regard Ali as the first Imam and consider him and his descendants the rightful successors to Muhammad, all of which are members of the Ahl al-Bayt, the household of Muhammad. This disagreement split the Ummah (Muslim community) into the Sunni and Shia branches.

Muslim sources, especially Shia ones, state that since Muhammad's time, Ali was the only person born in the Kaaba sanctuary in Mecca, the holiest place in Islam. His father was Abu Talib and his mother was Fatima bint Asad, but he was raised in the household of Muhammad, who himself was raised by Abu Talib, Muhammad's uncle, and Ali's father. When Muhammad reported receiving a divine revelation, Ali was the first male to accept his message, dedicating his life to the cause of Islam.
