Paper Mario: The Origami King is an upcoming 2020 role-playing video game developed by Intelligent Systems and published by Nintendo for the Nintendo Switch console. It is the sixth game in the Paper Mario series, part of the larger Mario franchise, and is scheduled for release on July 17, 2020.

As with the previous Paper Mario games, The Origami King is a role-playing video game (RPG). The player controls a paper version of Mario in a 3D world that fuses other paper and three-dimensional constructs, including origami sculptures. The player explores the game's overworld to collect coins and items, encounter non-playable characters (NPCs), solve various puzzles based on the paper world concept, and upon encountering enemies, enter into combat to defeat them. Mario can gain various partners over the course of his journey that help to solve puzzles and join in battle. For example, Olivia helps give Mario "1000-Fold Arms" that can reach up to tear back parts of paper environment to reveal secrets. The game uses a ring based combat system: with the player as Mario at the center of multiple rings, they will need to line up enemies that sit on sections of these rings within a short period and then choose an attack to strike at those enemies that fall within the same arc across all ring, after which the enemies will have a chance to attack.
