A city car (also known as urban car or mini) is a small car intended for use primarily in an urban area.

City cars are sold worldwide and most automotive industry manufacturers have one or two in their line-up. In North America, city cars are often referred to simply as "subcompacts" alongside the superminis. These kinds of car are also usually known as the A-segment across Europe. In Japan, the kei car (軽自動車, keijidōsha^?, lit. "light automobile") is a specific type of city car. To receive legal classification as a kei car (along with the added registration discounts and benefits), the vehicle must meet specific size criteria in both physical dimensions and engine capacity. For 'city cars' in Japan, the definition is informal and imprecise.
