Paper Mario: The Origami King is the sixth instalment in the Paper Mario series. It was released on the Nintendo Switch worldwide on July 17, 2020. The game follows Mario opposing an evil army of origami characters known as Folded Soldiers. They are ruled by the Origami King, King Olly and have taken over the Mushroom Kingdom.

The game follows the gameplay style of Paper Mario: Sticker Star, and Paper Mario: Color Splash. Role-playing elements are less. There are more action-adventure mechanics. They focus on exploration and puzzle-solving in individual areas rather than emphasizing character growth over the entire game. Like the previous games, Paper Mario: The Origami King is focused around an aspect of arts and crafts. Paper Mario: Sticker Star had a focus on stickers. Paper Mario: Color Splash had a focus on paint. Paper Mario: The Origami King is focused around origami. The game's environments graphically resemble crafts. Many of the game's bosses are based around some kind of crafting tool. Paper Mario: The Origami King has levels that are directly connected rather than being segregated through a level select screen. Similar to Paper Mario: The Thousand-Year Door and Super Paper Mario, Bowser is not the primary antagonist in exchange for an original villain. Paper Mario: The Origami King does not feature a battle system which uses finite items for combat. It uses an original ring-based system which uses puzzle-solving instead of strategy.
