汽车设计（英语：Automotive design）是一门涉及汽车外观美术设计、工程学、以及人体工程学等范畴的专门行业。

现在一般所称的汽车设计是指汽车在美学与功能方面的工业设计，而非车辆工程设计，欧美有不少大学都将汽车设计从工业设计系中独立出来变成一个科系，称为交通工具设计系，但以汽车机车和脚踏车设计为主，飞机与船的设计另有专业科系，也有少数英国与澳洲的大学提供汽车设计博士学位。

除了美学艺术外汽车设计师需懂一部分工程方面的知识，但空气动力学的部分大都由专门的工程师负责，空气力学的理论颇为复杂仍有未知之处，还不能全由电脑仿真，须制做模型经过风洞实际测试，较好的空力设计有助于省油、降低噪音、增加行车稳定性与性能。汽车设计师也需要与车厂其他部门配合，根据市场喜好和产品定位、成本等修改设计，因此不是纯美学艺术的展现，许多车展上概念车的设计不会完全出现在生产版本上。

Automotive design is the profession involved in the development of the appearance, and to some extent the ergonomics, of motor vehicles or more specifically road vehicles.

This most commonly refers to automobiles but also refers to motorcycles, trucks, buses, coaches, and vans. The functional design and development of a modern motor vehicle is typically done by a large team from many different disciplines included within automotive engineering. Automotive design in this context is primarily concerned with developing the visual appearance or aesthetics of the vehicle, though it is also involved in the creation of the product concept. Automotive design is practiced by designers who usually have an art background and a degree in industrial design or transportation design.
