The Arab Champions League (Arabic: كأس الإتحاد العربي للأندية), previously known as the UAFA Club Cup and Arab Club Champions Cup, is an annual regional club football competition organised by the Union of Arab Football Associations (UAFA).
The tournament's first ever champions were Iraqi giants Al-Shorta SC, who defeated Lebanese side Nejmeh SC in the final over two legs in 1982. Al-Karkh SC of Iraq are the most successful club in the competition's history, having won the tournament three times under the name of Al-Rasheed SC. Saudi Arabian clubs have accumulated the most victories, with 8 wins. The title has been won by 17 different clubs, seven of which have the title more than once. Since the tournament changed its name and structure in 2003, only ES Sétif of Algeria have managed consecutive wins, successfully defending their title in 2008. The reigning champions are USM Alger, after beating Al-Arabi 3–2 on aggregate in the 2013 final. In 2015 the tournament's name was changed back to "arab champions league" for the 2015-2016 season
The competition was first known as the Arab Club Champions Cup, and established in 1982. In 2001, it merged with the Arab Cup Winners' Cup to form the new Prince Faisal bin Fahd Tournament for Arab Clubs, named after Faisal bin Fahd. Between 2003 and 2009, the competition was known as the Arab Champions League. In 2012 the competition was re-branded as the UAFA Club Cup in a partnership with World Sport Group.
