Robotech is a popular science fiction and anime franchise that was launched by an 85-episode animated television series about three successive extraterrestrial invasions of Earth. Within the context of the show, "Robotech" refers to Robotechnology, the advances in science and technology that came about from studying an alien starship that crashed on a South Pacific island. Robotechnology made possible the creation of giant robotic mecha, or fighting machines, many of which were capable of transforming into vehicles (especially fighter planes) for greater battlefield mobility.

Robotech was one of the first anime released in the United States that largely managed to preserve the complexity and drama of its original Japanese source material. Produced by Harmony Gold USA, Inc. in association with Tatsunoko Prod. Co., Ltd., Robotech is a story adapted with edited content and revised dialogue from the animation of three different mecha anime series: The Super Dimension Fortress Macross, Super Dimension Cavalry Southern Cross, and Genesis Climber Mospeada. Harmony Gold's cited reasoning for combining these unrelated series was its decision to market Macross for American weekday syndication television, which required a minimum of 65 episodes at the time (thirteen weeks at five episodes per week). Macross and the two other series each had fewer episodes than required since they originally aired in Japan as weekly series.

This combination resulted in a storyline that spans three generations as mankind must fight three destructive Robotech Wars in succession over a powerful energy source called "Protoculture": The First Robotech War (The Macross Saga) concerns humanity's battle against the giant Zentraedi warriors who are sent to earth to retrieve the wrecked starship that contains the last known source of Protoculture in the universe. In the Second Robotech War (The Robotech Masters), their rulers, the Robotech Masters, attempt to take up where the Zentraedi left off. In the Third Robotech War (The New Generation), the alien Invid have been attracted to earth by events that transpired at the end of the Second Robotech War, and it is up to returning elements of the Robotech Expeditionary Force to fight them off.
