A Nitro Course is a course in the Mario Kart series that has never appeared before, thus making them new courses. They have appeared in every Mario Kart title. Some of them will or have reappeared in later Mario Kart games as retro courses.
NOTE: From Mario Kart DS onwards, it is the last cup of the Retro Courses.
