A fighter pilot is a military aviator trained to engage in air-to-air combat, air-to-ground combat and sometimes electronic warfare while in the cockpit of a fighter aircraft. Fighter pilots undergo specialized training in aerial warfare and dogfighting (close range aerial combat). A fighter pilot with at least five air-to-air kills becomes known as an ace.

Fighter pilots are one of the most highly regarded and desirable positions of any air force. Selection processes only accept the elite out of all the potential candidates. An individual who possesses an exceptional academic record, physical fitness, healthy well-being, and a strong mental drive will have a higher chance of being selected for pilot training. Candidates are also expected to exhibit strong leadership and teamwork abilities. As such, in nearly all air forces, fighter pilots, as are pilots of most other aircraft, are commissioned officers.

Fighter pilots must be in optimal health to handle the physical demands of modern aerial warfare. Excellent heart condition is required, as the increased "G's" a pilot experiences in a turn can cause stress on the cardiovascular system. One "G" is equal to the force of gravity experienced under normal conditions, two "G"s would be twice the force of normal gravity. Some fighter aircraft can accelerate to up to 9 G’s. Fighter pilots also require strong muscle tissue along the extremities and abdomen, for performing an anti-G straining manoeuvre (AGSM, see below) when performing tight turns and other highly accelerated manoeuvres. Better-than-average visual acuity is also a highly desirable and valuable trait.
