A multirole combat aircraft is a combat aircraft intended to perform different roles in combat. These roles can include air to air combat, air support, aerial bombing, reconnaissance, electronic warfare, and suppression of air defenses.

A multi-role fighter aircraft is a type of military jet that is designed to perform a variety of combat missions rather than being specialized for a single role. These aircraft combine the capabilities of air-to-air fighters and air-to-ground attack aircraft, offering versatility and efficiency on the battlefield.

More roles can be added, such as aerial reconnaissance, forward air control, and electronic-warfare aircraft. Attack missions include the subtypes air interdiction, suppression of enemy air defense (SEAD), and close air support (CAS).

Multirole has also been applied to one aircraft with both major roles, a primary air-to-air combat role, and a secondary role like air-to-surface attack. However, those designed with an emphasis on aerial combat are usually regarded as air superiority fighters and usually deployed solely in that role, even though they are theoretically capable of ground attack. The Eurofighter Typhoon and Dassault Rafale are classified as multirole fighters; however the Typhoon is frequently considered an air superiority fighter due to its higher dogfighting prowess while its built-in strike capability has a lighter bomb load compared to contemporaries like the Rafale, which sacrifices air-to-air ability for a heavier payload.

For the US Navy, the F-14 Tomcat was initially deployed solely as an air-superiority fighter, as well as fleet defense interceptor and tactical aerial reconnaissance. By contrast, the multirole F/A-18 Hornet was designed as strike fighter while having only enough of an edge to defend itself against enemy fighters if needed. While the F-14 had an undeveloped secondary ground attack capability (with a Stores Management System (SMS) that included air-to-ground options as well as rudimentary software in the AWG-9), the Navy did not want to risk it in the air-to-ground role at the time, due to its lack of proper defensive electronic countermeasures (DECM) and radar homing and warning (RHAW) for overland operations, as well as the fighter's high cost. In the 1990s, the US Navy added LANTIRN pods to its F-14s and deployed them on precision ground-attack missions.

Some aircraft, like the Saab JAS 39 Gripen, are called swing-role, to emphasize the ability of a quick role change, either at short notice, or even within the same mission. According to the Military Dictionary: "the ability to employ a multi-role aircraft for multiple purposes during the same mission."

According to BAE Systems, "an aircraft that can accomplish both air-to-air and air-to-surface roles on the same mission and swing between these roles instantly offers true flexibility. This reduces cost, increases effectiveness and enhances interoperability with allied air forces".

"[Swing-role] capability also offers considerable cost-of-ownership benefits to operational commanders."
