Otakuthon is a Canadian anime convention promoting Japanese animation (anime), Japanese graphic novels (manga), related gaming and Japanese pop-culture (music, cinema, television). It is held annually for 3 days in downtown Montreal during a weekend in August. It is a non-profit, fan-run anime convention that was initiated by Concordia University's anime club, named Otaku Anime of Concordia University (Otaku Anime for short). The name "Otakuthon" is a portmanteau of the Japanese word "otaku" and "marathon". Otakuthon strives to be a bilingual (French and English) event, having programming, the masquerade and the program book in both official languages. The first edition of Otakuthon was held in 2006 in early June, but later moved to early-mid August / late July from 2007 onward. The most recent edition, Otakuthon 2025, was held on August 8–10, 2025 at the Palais des congrès de Montréal.
