Flying Shark, known as Sky Shark in North America, is a 1987 vertically scrolling shooter arcade video game originally developed by Toaplan and published by Taito in Japan, Romstar in North America and Electrocoin in Europe. Controlling the titular biplane, the players must fight endless waves of military vehicles while avoiding collision with their projectiles and other obstacles. The plane has a powerful bomb at its disposal that can clear the screen of enemies when fired. It was the third shoot 'em up game from Toaplan, and their eighth video game overall. Flying Shark was ported to multiple systems, each version created by different third-party developers. The game proved to be a success for Toaplan among players in Japanese arcades and garnered mostly positive reception from western critics, however the game was met with mixed response from magazines, specifically the home conversions. In 1989, a sequel titled Fire Shark was released. The rights to the title are owned by Tatsujin, a Japanese company formed by Masahiro Yuge.

The bombs are powerful weapons capable of obliterating any enemy caught within its blast radius. Various items are scattered through every stage that appear by destroying certain enemies: Shooting down colored waves of enemy planes spawn items like "S" power-up icons, point bonuses and extra lives. Certain enemies on the ground spawn "B" icons that increases the player's bomb stock when destroyed. Every time the player lands at a runway beyond the first takeoff, the amount of bombs multiply 3000 points to the player's total score. Players are given three lives initially and bonus lives are awarded at 50000 points and thereafter. The game employs a checkpoint system in which a downed single player will start off at the beginning of the checkpoint they managed to reach before dying. Getting hit by enemy fire will
