Hotel Mario is a computer puzzle game developed by Fantasy Factory and published by Philips Interactive Media and Nintendo for the CD-i in 1994. The primary character of the game is Mario, who must find Princess Toadstool by going through seven Koopa hotels in the Mushroom Kingdom. Every hotel is divided into multiple stages, and the objective is to close all doors on each stage. Defeating a Koopaling on the hotel's final stage takes the player to the following building.

After Nintendo decided not to have Philips create an add-on for the Super NES, they gave Philips permission to use five of their characters in games for Philips' CD-i. The games were given little time to be developed and little funding, and Nintendo only gave cursory input.

The games resulting from the license were widely criticized, with Hotel Mario being regarded as one of the worst Mario-centered games, due to the animation of the shutting doors, the unresponsive controls and especially known for the cutscenes that used full motion video. The CD-i was considered a commercial failure and the games became valuable due to their rarity.
