Hot Wheels is a brand of 1:64, 1:43, 1:18 and 1:50 scale die-cast toy cars introduced by American toy maker Mattel in 1968. It was the primary competitor of Matchbox until 1997, when Mattel bought Tyco Toys, then-owner of Matchbox.

The first sixteen Hot Wheels cars, sold for 59 cents each, were introduced into the market in 1968, and they featured redline tires, spectraflame paint, a metal collector button, and some had roofs painted black to look like vinyl.

Hot Wheels were conceived to be more like "tricked out" cars, as compared to Matchbox cars which were more city or "real life" cars. There were sixteen castings released in 1968, eleven of them designed by Harry Bentley Bradley. The first one produced was a dark blue Custom Camaro. Bradley was from the car industry and had designed the body for the (full-sized) Dodge Deora concept car and the Custom Fleetside, (based on his own customized 1968 Chevrolet C-10 Fleetside).

In addition to the cars themselves, Mattel produced a racing track set (sold separately). Though it would be updated throughout the years, the original track consisted of a series of brightly colored orange road sections (pieced together to form an oblong, circular race track), with one (or sometimes two) "super chargers" (faux service stations through which cars passed on the tracks, featuring battery-powered spinning wheels, which would propel the cars along the tracks).
