Festiwal Fantastyki Pyrkon) (commonly known as Pyrkon) is a Polish fan convention held annually in Poznań on the first weekend after the spring equinox and dedicated to an integration of Science fiction fandom and a promotion of science-fiction/fantasy literature, comics, film, television, video games, RPG, LARP, board games, collectible card games and miniature wargaming.

Pyrkon has been a non-profit convention from its beginning, and all organizers, lecturers and gofers are volunteers.

Due to the increasing number of visitors, in 2011 the convention moved to the present location, the Poznań International Fair and the Liceum ogólnokształcące nr 2 in Poznań (Liceum Ogólnokształcące nr 2 w Poznaniu).

Usually it is also the weekend when Daylight saving time begins – participants are informed in a convention guide book and on posters of the need to adjust their timepieces.

According to a longtime chairman of the Second Age Club Piotr Derkacz this was actually supposed to be a temporary name, until they would come up with a more serious one.
