List of unofficial Mario media

Unlicensed developers and fans have created unofficial media relating to the Mario franchise. Such media include video games, ROM hacks, level editors, live action adaptations, and animations.

Due in-part to the franchise's popularity, some of these unlicensed works have received critical attention. In September 2016, Nintendo issued over 500 DMCA takedown requests for various fan games hosted at Game Jolt based on their intellectual properties. All of these games have been taken down. While some of these pieces of media have been deemed to fall under fair use, many have not, with the specifics of rulings often depending on the country in which the notice for copyright infringement was given.
