An antique car is an automobile that is an antique. Narrower definitions vary based on how old a car must be to qualify. The Antique Automobile Club of America defines an antique car as over 25 years of age. However, the legal definitions for the purpose of antique vehicle registration vary widely. The antique car era includes the Veteran era, the Brass era, and the Vintage era, which range from the beginning of the automobile up to the 1930s. Later cars are often described as classic cars. In original or originally restored condition antiques are very valuable and are usually either protected and stored or exhibited in car shows but are very rarely driven.

The Brass Era is an American term for the early period of automotive manufacturing, named for the prominent brass fittings used during this time for such features as lights and radiators. It is generally considered to encompass 1896 through 1915, a time when cars were often referred to as horseless carriages.
