Eversion (from the verb "evert") is the process of turning inside-out. Eversion may refer to:

• Eversion (kinesiology), the anatomical term of motion denoting the movement of the sole of the foot away from the median plane
• Eversion (mathematics), the process of turning a shape inside out without causing creases; in particular, sphere eversion
• Eversion (video game), a platform video game made by Guilherme S. Tows
• In sea cucumbers, a form of autotomy in which the animal ejects its internal organs as a defensive strategy

Eversion is a short platform game for Microsoft Windows by Zaratustra Productions. It features a small flower-like protagonist named Zee Tee, who is on a quest to rescue a princess named Nehema from the evil Ghulibas of the North, collecting gems along the way, much in the plot-style of early Mario games. Each level consists of a set of parallel realities, each of which features different hazards, a unique artistic style, and a distinctive soundtrack. By using Zee Tee's ability to "evert" from one reality to another, the player can navigate him through obstacles to reach his goal.

The opening screen and the first few levels are quite cheerful and colorful, but the environment becomes gradually more deranged and disturbing as the player progresses into other levels of Eversion. The game was inspired by a quotation from H. P. Lovecraft and it features a warning on the intro screen that it is "not intended for children or those of a nervous disposition".

Eversion is free to download, but a high-definition version can only be purchased for $4.99 on Steam. Later versions of the free game feature an updated soundtrack and a completely overhauled final level, while the high-definition version features additional options and more detailed artwork.
