Asterix: The Secret of the Magic Potion (French: Astérix: Le Secret de la Potion Magique) is a 2018 French animated adventure family comedy film co-directed by Alexandre Astier and Louis Clichy. A sequel to 2014's Asterix: The Mansions of the Gods, the screenplay by Astier is based on the Asterix comic book characters created by René Goscinny and Albert Uderzo. This is the first Asterix production not to feature Roger Carel as the voice of Asterix, due to his retirement and later death. Asterix is instead voiced by Christian Clavier, who previously played the character in Asterix and Obelix vs. Caesar and Asterix & Obelix: Mission Cleopatra.

The film was released in France on 5 December 2018 by SND. Icon Film Distribution released the film's English dub in Australia starting 30 May 2019.
