Turn A Gundam (∀（ターンエー）ガンダム, Tān Ē Gandamu), also stylized as ∀ Gundam, is a 1999 Japanese mecha anime series produced by Sunrise, and aired between 1999 and 2000 on Japan's FNN networks. It was created for the Gundam Big Bang 20th Anniversary celebration, and is the eighth installment in the Gundam franchise. It was later compiled in 2002 into two feature-length films entitled Turn A Gundam I: Earth Light and Turn A Gundam II: Moonlight Butterfly.

Turn A Gundam was directed by Yoshiyuki Tomino, who is the main creator of the Gundam franchise, and who had written and directed many previous Gundam works. Tomino created the series as a means of "affirmatively accepting all of the Gundam series", which is reflected in the series title's use of the Turned A, a mathematical symbol representing universal quantification.
