List of sponsors debuting in Mario Kart 64

This a list of the sponsors that have only appeared in Mario Kart 64. For sponsors that have appeared in the other Mario Kart games, see the list of recurring sponsors in the Mario Kart series.

Koopa Air
Koopa Air is a sponsor that appears in Mario Kart 64. Presumably, it is an airline with some relation to Koopas. The logo consists of company name written in an italicised all-capitals font with a purple and blue gradient on a white background. In Japan, the logo used a different color scheme with yellow text and a dark blue background. This resembled the logo, which was a major  advertiser at the time, and was likely removed in the western versions to prevent a lawsuit from the company. It is advertised by means of trackside banners and signs.

Luigi's
Luigi's (known as Luigip in Japan) is a sponsor that appears in Mario Kart 64. Although it is unclear what the sponsor does, it appears to have some relation to Luigi. The logo consists of the name written in a red font on a yellow background. The Japanese version is based on the logo of, which was a major advertiser at the time, using the same font and color scheme. The background is yellow with the company name written on it in a black font with lines through the middle of the letters, with the dot of the second "I" lacking the line and being colored red. On the left of the text is a stylized version of Luigi's eyes, nose and mustache in black within a square outline with rounded corners. The reference in both the name and logo was removed in the western versions presumably to prevent a lawsuit from Agip, although the Japanese logo was later adapted in Mario Kart Wii into a new Luigi Grand Prix logo. It is advertised by means of trackside banners and signs.

Mario Star
Mario Star (known as Marioro in Japan) is a sponsor that appears in Mario Kart 64. Although it is unclear what the sponsor does, it appears to have some relation to Mario. The logo consists of the company name written in an all-capitals blue font on a white background with a red line above and below the text. The Japanese logo is based on that of, which was a major advertiser when the game was released, and also where the Japanese name comes from. It consists of the company name in a black serif font on a white background, with a red rectangle with a triangle shape removed from the top on the right, an inverted version of the Marlboro logo. This was likely changed in the western versions of the game to avoid a lawsuit from Marlboro or to remove the tobacco reference. It is advertised by means of signs and trackside banners.
