GoShogun (戦国魔神ゴーショーグン, Sengoku Majin GōShōgun) is a Japanese super robot anime series created by Takeshi Shudo. It was produced and aired in 1981 in Japan, with a movie special released in 1982 and a film sequel, GoShogun: The Time Étranger or Time Stranger, in 1985. Its title has been variously translated into English as "Demon God of the War-Torn Land GoShogun", "Warring Demon God GoShogun", and "Civil War Devil-God GoShogun", but in the US and parts of Europe it is primarily known as Macron 1, the title of its North American adaptation.

The GoShogun series and its film sequel, The Time Étranger, were both written by Takeshi Shudo and directed by Kunihiko Yuyama. The series is noted for its witty dialogue and lighthearted parody of its own genre conventions. The Time Étranger shifts away from the original genre, leaving the robot aside entirely to focus on the strong and complex heroine. It has been praised for its serious tone, psychological intensity, and handling of mature themes.
