Hot Wheels mini cars are small, die-cast toy cars that have been a popular brand by Mattel since 1968. They are known for their fast-rolling wheels and detailed designs, which are often based on real-life vehicles, as well as futuristic or fantastical concepts.

While the term "mini car" could apply to any of their products, Hot Wheels cars are most commonly associated with their standard 1:64 scale. They are sold individually in blister packs or in multi-car sets and are used for both play on their signature orange tracks and for collecting by enthusiasts of all ages.
