徽章工程，又称品牌工程，为英文“badge engineering”直译而来。特别常见于汽车产业上，其他产业也有类似应用，例如常见的姊妹车、兄弟车。由于高成本的设计和工程制造一台新的产品原型，抑或创建一个新品牌需要花很长的时间得到市场的考验。徽章工程通常是一个很有成本效益的工程方式将单一个产品多次重新挂上其他的标志。这样形式的工程方式关系源于汽车内部或外部的商标的价值差异，透国换牌来达到宣传品牌或是抬高价格的目的。起初只有在于不同生产商的商标上，后来典型的例子包含一些细微的改型，例如车头灯和尾灯，前后保险杆，以及其他汽车前后部位的外显设备。甚至包含引擎与传动设备。

Rebadging, sometimes called badge engineering, is the application of a different brand or trademark (badge, logo or manufacturer's name/marque) to an existing product (e.g., an automobile) and subsequently marketing the variant as a distinct product. Due to the high cost of designing and engineering a new model or establishing a brand (which may take many years to gain acceptance), it is less expensive to rebadge a product once or multiple times than to create different models. The costs of product development and manufacturing tools are spread over more vehicles, achieving economies of scale.
