A **mathemagician** is a mathematician who is also a magician. The term "mathemagic" is believed to have been introduced by Royal Vale Heath with his 1933 book "Mathemagic".^{[1]}

The name "mathemagician" was probably first applied to Martin Gardner, but has since been used to describe many mathematician/magicians, including Arthur T. Benjamin,^{[2]} Persi Diaconis,^{[3]} and Colm Mulcahy.^{[4]} Diaconis has suggested that the reason so many mathematicians are magicians is that "inventing a magic trick and inventing a theorem are very similar activities."^{[5]}

Mathemagician is a neologism, specifically a portmanteau, that combines mathematician and magician. A great number of self-working mentalism tricks rely on mathematical principles, such as Gilbreath's principle. Max Maven often utilizes this type of magic in his performance.

The Mathemagician is the name of a character in the 1961 children's book *The Phantom Tollbooth*. He is the ruler of Digitopolis, the kingdom of mathematics.
