Classic course

A classic course,  formerly known as an Extra Track in Mario Kart: Super Circuit and as a Retro Course from Mario Kart DS to Mario Kart 7, is a course that appears in a Mario Kart game following its introduction. They first appeared in Mario Kart: Super Circuit in Extra Cups, which include the Extra Mushroom, Flower, Lightning, Star, and Special Cups, each containing four courses from Super Mario Kart. Classic courses systematically appear in every Mario Kart game since Mario Kart DS, with the Shell Cup, Banana Cup, Leaf Cup, and Lightning Cup, each of them featuring four classic courses from various games of the series. Starting with the DLC cups in Mario Kart 8, classic courses can appear in the same cup as new courses. The Booster Course Pass DLC for Mario Kart 8 Deluxe consists mostly of classic courses, which are also referred to as Booster Courses.

Starting with Mario Kart DS, classic courses are distinguished by a prefix in their names indicating the game they originate from. These prefixes are abbreviations of the name of the console that the game was released on; "SNES" refers to Super Mario Kart, "N64" to Mario Kart 64, "GBA" to Mario Kart: Super Circuit, "GCN" to Mario Kart: Double Dash!!, "DS" to Mario Kart DS, "Wii" to Mario Kart Wii, "3DS" to Mario Kart 7, and "Tour" to Mario Kart Tour (only for city races).

Prior to Mario Kart 8, classic courses were near-identical to their original counterparts, usually only receiving graphical updates, such as expanding the space and blocks in SNES and GBA courses. In Mario Kart DS, however, some classic courses appear to be scaled down in graphics due to limitations of the Nintendo DS. In Mario Kart Wii and Mario Kart 7, classic courses appear almost identical to their original versions, besides added underwater and gliding sections in the latter game. Starting in Mario Kart 8, most classic courses are completely redesigned with HD graphics, usually featuring newer mechanics such as underwater, gliding, and (except in Mario Kart Tour) anti-gravity. They also tend to feature other new details, including completely new backgrounds or even changes to the track's layout. Additionally, Mario Kart 8 features newly remastered music for all classic courses, whereas classic courses in previous Mario Kart games tend to retain their original music (though they were sometimes altered due to system limitations, primarily for the Game Boy Advance and Nintendo DS). Mario Kart Tour's classic courses vary in similarity to their original versions, and the music is almost always either the original arrangement or from Mario Kart 7, with the only exceptions being the non-Bowser's Castle GBA courses (which all use new arrangements), the Ghost Valley courses and (which use the Mario Kart Wii arrangements), and the Choco Island courses (which use the Mario Kart DS arrangement).

Mario Kart Tour
Mario Kart Tour features 52 courses from previous entries, being the most of any Mario Kart game, as well as a new reroute of named Kalimari Desert 2 which is categorized as a classic course in-game. Courses in Mario Kart Tour are not arranged into set cups like in the other games, as the cups and available courses change between each tour. The courses below are listed in the order in which they were introduced to the game, with listed first due to it being the track used for the tutorial before the new players get to access the cups. All of Mario Kart 7's classic courses also returned in the game. Screenshots of in this game have also been shown, but the course has yet to be featured in a tour.

While Sky-High Sundae was added to this game after it was added to the Mario Kart 8 Deluxe – Booster Course Pass, it is not officially considered a classic course. It has instead been marketed as a new course in both games.

Table of classic race courses
Courses highlighted in red have yet to appear as classic courses in a later Mario Kart installment. A dash (–) indicates that the course appears as a new course in its respective game and therefore cannot appear as a classic course in it or, unless noted otherwise, in a previous installment.

Mario Kart: Super Circuit
While no classic battle courses appear in Mario Kart: Super Circuit, unused tilemaps and minimaps exist for all four battle courses from Super Mario Kart. Unlike other courses in the game, which are stored in chunks, these are stored in one piece, the same way Super Mario Kart stores them.
