Jamal al-Haidari (Arabic: جمال الحيدري, died 1963) was an Iraqi communist politician.
Al-Haidari dedicated his energy into combating the Communist Party and its leader, Basim, in particular.
The 'Clique of Foor' accused Adil and al-Haidari of spoiling the relations with Abd al-Karim Qasim.
In the end a settlement was reached (with as-Sayegh unofficially bargaining on behalf of the then government), al-Haidari and Abdullah were relieved of their party duties due to 'health reasons' and exit visas were provided (through as-Sayegh's government contacts) for them to travel to Moscow.
Along with Abd ul-Jabbar Wahbi and Salih al-Abli, al-Haidari established a new 'Central Party Leadership'.
