Ordyne[a] is a horizontal scrolling shooter arcade game, which was released by Namco in 1988 only in Japan.

It features a cameo from Pac-Man, as the "Stock bomber shot" - and the arcade version was also included in Namco Museum Volume 4 for the Sony PlayStation.

The TurboGrafx-16 version was released on the Wii's Virtual Console on May 7, 2007 in North America and on August 21, 2007 in Japan; it is officially described by Namco as a "comical action shooter".

The enemies all follow preset patterns, and killing a group of smaller ones or a larger one leaves crystals behind that can be collected and exchanged for special weapons, extra lives, and even more crystals at the "Kūchū IN" run by the blue-haired woman Miyuki-chan (みゆきちゃん, Miyuki Chan) and by firing out marbles at the extendable rotating target of the big white-handed robot Dream Co., Ltd. (夢有限会社, Yūme Yūgengaisha).

In Japan, Game Machine listed Ordyne on their November 1, 1988 issue as being the second most-successful table arcade unit of the month.
