Origami paper, also known as origami folding paper or simply origami sheets, is a specialised type of paper used for the Japanese art of paper folding, known as origami.

Origami paper typically comes in square sheets, although rectangular sheets can also be used. The most common size is around 15 centimeters (6 inches) per side, but sizes can vary from miniature squares to larger sheets depending on the project and personal preference. They are usually thin and lightweight, allowing for easy folding and shaping. The thickness can vary slightly depending on the brand and quality of the paper, but it is generally thinner than regular printer paper.
