Fictional military aircraft are imagined military aircraft which are used in fiction, in its various media, but do not exist in the real world. These aircraft may be conjectured variants of real-world aircraft or they may be completely fabricated by the author. Some may be physically impossible.

The Allied Nations' Black Eagles are high-speed VTOL jets used mostly by The Republic of Korea in Command & Conquer: Red Alert 2.

Black Eagles feature forward-swept wings but otherwise resemble a Harrier Jump Jet. They are loaded with powerful missiles used for engaging surface targets. Black Eagles are usually painted black in reference to their name. They most likely were inspired by the Russian Su-47 Berkut, which is Russian for Golden Eagle. They are also named after the Republic of Korea Air Force (RoKAF) aerobatic team, the Black Eagles.

The XF-18 Scavenger is a highly capable all-weather reconnaissance plane described in Michael Crichton's novel The Andromeda Strain.

In the 1980s, a gap appeared in the designation system for U.S. military aircraft, between the F/A-18 Hornet and the F-20 Tigershark. This unseen F-19 was speculated to be a top-secret stealth fighter in U.S. service. Various depictions of F-19s have since appeared in fictional works, as well as in the usually accurate Jane's All the World's Aircraft publication (as the Lockheed RF-19 and XST).
