Summoner is an action role-playing game developed by Volition and published by THQ for the PlayStation 2. It was released as a launch title for the console and was subsequently ported to Microsoft Windows and Mac OS the following year. In the game, the player plays the role of Joseph and can assemble a team of compatriots and summon powerful monsters. The game has a world map, involved storyline, and unique hybrid combat system involving real-time and turn-based mechanisms.

A sequel, Summoner 2, was released in 2002.[2] After the bankruptcy of publisher THQ in December 2012, the Summoner franchise was acquired by Nordic Games, now THQ Nordic, who released the PlayStation 2 version on the PlayStation 4 and PlayStation 5 in June 2024.
