Hollande's aircraft, carrying about 15 tonnes of humanitarian aid set to be delivered to the Kurdish capital of Erbil, landed in Baghdad on Friday. France is preparing to take part in possible US-led air strikes against the armed group.
France, which has been supplying arms to Kurdish forces fighting Islamic State fighters since August, has also been flying in humanitarian supplies to help civilians affected by the conflict.
The latest aid supply is set to be delivered to Erbil following talks between Hollande and his Iraqi counterpart Fuad Masum, parliament speaker Salim al-Juburi, and prime minister Haider al-Abdadi.
Hollande travelled to Baghdad with Jean-Yves Le Drian and Laurent Fabius, respectively France's defence and foreign ministers.
