The Vietnam Air Gallantry Cross (Vietnamese: Phi-Dũng Bội-Tinh) was a military decoration of South Vietnam which was issued during the years of the Vietnam War.

The Air Gallantry Cross was awarded for meritorious or heroic conduct while engaged in aerial combat.

The Air Gallantry Cross was occasionally awarded to members of foreign militaries, but only if an air combat action was performed which directly benefitted Vietnamese war efforts.

Separate decorations, known as the Vietnam Gallantry Cross and Vietnam Navy Gallantry Cross, were also issued for general service and naval achievement.

The Air Gallantry Cross was awarded to Naval Aviators operating off aircraft carriers in the Tonkin Gulf and to United States Marine aviators operating from bases in South Vietnam.
