Nadeo is a French video game developer, based in Paris. They are the developers of the TrackMania, QuestMania, ShootMania and Virtual Skipper series of video games.

In February 2010, advertisements began appearing occasionally on TrackMania load screens for Nadeo's ShootMania and QuestMania, presumably a first-person shooter and RPG, respectively. There were websites created for both of these games: and, currently offering nothing in exception of backgrounds, presenting its game through advertisements shown in TrackMania. On October 5, 2009, the company was acquired by French publisher Ubisoft.
