The PC class was a type of standard gauge passenger steam locomotive on Iraqi State Railways.

[1] In 1941 Robert Stephenson and Hawthorns built four Pacific locomotives for ISR to haul the new through service on the Iraqi section of its route.

The PC class were named after Iraq's four principal cities: Baghdad, Mosul, Basra and Kirkuk.

[2] Thereafter the April 1941 Iraqi coup d'état installed a government allied to Fascist Italy and Nazi Germany and delivery of the remaining members of the class was delayed until after the British invasion of Iraq in May 1941 and invasion of Vichy-ruled Syria and Lebanon in June and July.

[3] In March 1967 locomotives 1501, 1502 and 1503 were disused, stored at Shalchiyah railway works and awaiting disposal.
