Ja'far ibn Fallah or ibn Falah was a Berber general of the Kutama tribe from Kabylia in the service of the Fatimid Caliphate.[1][2] He led the first Fatimid attempt to conquer Syria in 970–971, but his attack on Byzantine-held Antioch was repulsed, and he lost his life in June 971 fighting against the Qarmatians.
