老爷车（vintage car）是二战后人们泛指1919年至1930年之间制造，早期曾使用但现在仍可运转行走的老式汽车，不过现在都指那些车龄超过20-25年以上的车辆。

「老爷车」一词，最早出现在1973年英国出版的一本《名人与老爷车》的杂志上，尽管它的直译应该是「经典的古老汽车」，但由于「老爷车」这个词强烈的拟人色彩，此名称很快得到了各国汽车界人士的认可，并迅速蔓延，成为世界各地爱好者对老式汽车的统一称谓。

但是至今没有一个公认的标准定义，汽车史学家及老爷车爱好者仍在争论不休。美国老爷车俱乐部把其属意的品牌或车型（如：1925-1948年间生产）列为完全古典车（FULL CLASSIC），其定义为「非凡的汽车，拥有优良设计，高工艺标准及制作」，取向偏好美国品牌，欧洲产品则有沧海遗珠之憾。

An antique car, in the general sense of the term, is an automobile that is an antique. Narrower definitions vary based on how old a car must be to qualify. In the United States, an antique car is generally defined as a car over 25 years of age, this being the definition used by the Antique Automobile Club of America. 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.
