Air Duel (エア・デュエル, Ea Dyueru) is a vertically scrolling shooter game released for arcades by Irem in 1990.

It was followed by an unofficial sequel called Air Assault in the west and Fire Barrel (ファイアーバレル) in Japan.

The player selects from a jet fighter or attack helicopter, shoot enemies in the air and ground, collect power-ups, and defeat bosses to advance levels.

The underwater path of the first mission of Metal Slug 3 features a melody which is a remix of Air Duel's 3rd & 10th stages' theme.

In Japan, Game Machine listed Air Duel on their July 15, 1990 issue as being the fourth most-successful table arcade unit of the month.
