Dino Mech Gaiking (大空魔竜ガイキング, Daikū Maryū Gaikingu, lit. Sky Devilsaur Side King) is a Japanese Super Robot mecha anime series produced by Toei Animation. For distribution purposes, Toei refers to this television series as Dino-Mecha Gaiking or simply Gaiking.

It ran from April 1976 through January 1977 and consisted of 44 episodes of 25 minutes each. Gaiking was notable for being one of the few super robot series to take place in real places outside Japan, and for being the first Super Robot series to have a mobile carrier for the chief robots. In the US, Gaiking was part of Mattel's popular Shogun Warriors import toy line of the late 1970s and Jim Terry's Force Five anthology series. In 2005, a re-imaging titled Gaiking: Legend of Daiku-Maryu was produced.
