Major Mariam al-Mansouri, 35, "led the squadron" of UAE fighter jets that participated in raids Tuesday against the extremists, an Emirati source familiar with the matter said.
The UAE did not confirm officially that a woman was among the pilots that conducted the raids.
Mansouri is reportedly the first female UAE pilot of a fighter jet. She graduated from Abu Dhabi's Khalifa bin Zayed Air College in 2007 and is veteran pilot of F-16 warplanes.
Washington has said the United Arab Emirates, Saudi Arabia, Bahrain and Jordan, took part in the strikes on the Islamic State, which has seized swaths of Iraq and northern Syria.
Saudi Arabia on Wednesday released photographs of eight airmen it said were involved in Tuesday's US-led operations.
