Football Club Abu Muslim (Persian: باشگاه فوتبال ابومسلم خراسان, Bashgah-e Futbal-e Abumislâm-e Xorasan), commonly known as Abu Muslim, is an Iranian football club based in Mashhad, Razavi Khorasan, that competes in the League 3.

The club was founded in 1970 and is named after Abbasid-era Persian general Abu Muslim, who led the Abbasid Revolution that toppled the Umayyad dynasty.

Abu Muslim holds a long-standing enmity with provincial rivals Payam Khorasan known as the Mashhad derby.

After defeat in the tournament, it was decided that for Khorasan to have a powerful football team, Abu Muslim and Aria must merge.

Three brothers helped to merge the clubs, and Abu Muslim was able to make it to the 1975 Takht Jamshid Cup, which was the top football league in Iran before the Iranian revolution.

Abu Muslim made it to the newly established Azadegan League and participated during the 1990–91 and 1991–92 seasons, but was relegated after only two years.

Abu Muslim had been in a poor financial situation that season, as Khoshgovar had stopped being its sponsor.

Abu Muslim's only revenue came from advertisements and support from club fans, but surprisingly won promotion.

Because of the financial problems suffered by the club, On 7 September 2014 the Ministry of Youth Affairs and Sports declared the bankruptcy of F.C.
