Origamics: Mathematical Explorations Through Paper Folding is a book on the mathematics of paper folding by Kazuo Haga [ja], a Japanese retired biology professor.

It was edited and translated into English by Josefina C. Fonacier and Masami Isoda, based on material published in several Japanese-language books by Haga, and published in 2008 by World Scientific.

It is divided into ten chapters,[3] exploring concepts in paper folding that are "so simple that they could be discovered by middle- or high-school students".

[1] The book begins with the exploration of a single fold of a corner of a square to a midpoint of an opposite edge, and its analysis involving the geometry of the 3–4–5 right triangle.

These parts use only elementary methods in Euclidean geometry, such as the Pythagorean theorem and the use of triangle centers,[1] and may be best omitted when presenting this material to students.
