Raiden (雷電, Raiden) is a 1990 scrolling shooter arcade game that was developed by Seibu Kaihatsu. It was the first game in the Raiden series of scrolling shooter arcade games. Raiden first made its debut in September 1990. The game was distributed in Japan by Tecmo, North America by Fabtek, Taiwan by Liang HWA Electronics, Korea by IBL Corporation, Hong Kong by Wah Yan Electronics, and a few other countries such as Malaysia, though the publishers in those countries are unknown.

The title in Japanese translates to "Thunder And Lightning". Rai means thunder, and den means lightning. The closest English approximation of the pronunciation is /RHY-den/, not /RAY-den/. "Raiden" is the name of a Japanese WWII Fighter.

Raiden consists of eight vertical scrolling missions where the player maneuvers the Raiden craft dodging and destroying enemy robots, buildings, ground targets, and aircraft. There are bombs and missile powerups as well as collectable medals which add to the score. When player dies, the fighter's fragments become projectiles that damage enemies.

After defeating the Stage 8 boss, the mission is completed, and player receives 1 million points for each completed loop. Afterwards, it will start back to Stage 1. This time around, enemies shoot faster and at a more rapid rate.
