基于组件的软件工程（Component-based software engineering，简称CBSE）或基于组件的开发（Component-Based Development，简称CBD）是一种软件开发范型。它是现今软件复用理论实用化的研究热点，在组件对象模型的支持下，通过复用已有的构件，软件开发者可以“即插即用”地快速构造应用软件。这样不仅可以节省时间和经费，提高工作效率，而且可以产生更加规范、更加可靠的应用软件。

Component-based software engineering (CBSE), also known as component-based development (CBD), is a branch of software engineering that emphasizes the separation of concerns in respect of the wide-ranging functionality available throughout a given software system. It is a reuse-based approach to defining, implementing and composing loosely coupled independent components into systems. This practice aims to bring about an equally wide-ranging degree of benefits in both the short-term and the long-term for the software itself and for organizations that sponsor such software.
