Battle Shark (バトルシャーク) is a first-person shoot 'em up released as an arcade video game by Taito in 1989.

Power-up targets appear throughout the games, which can increase the supply of torpedoes, repair damage, or add extra firepower.

According to the description in the game's attract mode introduction, "extremely brutal fighting has been taking place on land, and now the battlefield is expanding into the oceans."

Battle Shark, with its driver, a navy soldier, must fight its way through hordes of enemy submarines, boats, and vehicles to track down the fortress, and ultimately destroy it.

In Japan, Game Machine listed Battle Shark on their May 1, 1990 issue as being the sixth most-successful upright arcade unit of the month.
