Darius Gaiden is a 1994 horizontal-scrolling shooter arcade game developed and published by Taito. The fifth entry in its Darius series, players control a starship named the Silver Hawk in its mission to destroy the Belsar empire before it wipes out the population of planet Darius. Gaiden adds several new features to the core concepts of its predecessors, including screen-clearing black hole bombs and the ability to capture mid-level bosses. The game has been ported to several consoles, including the Sega Saturn and PlayStation.

Darius Gaiden was released for Windows in 1997, which was subsequently re-released in North America in 2004.
