电脑辅助软件工程（英语：computer-aided software engineering，缩写：CASE）是指使用软件工具辅助软件的开发及维护。

1980年代晚期研发出电脑辅助软件工程工具，能够在前端协助画出数据流程图、实体关系图及分析设计的保存数据、检查错误漏失等；把规格确定后，后端自行产生TURBO C、PASCAL的代码。整体而言，可节省系统开发人员许多时间。

知名的电脑辅助软件工程工具分为以下几类：

Computer-aided software engineering (CASE) is the domain of software tools used to design and implement applications. CASE tools are similar to and were partly inspired by Computer Aided Design (CAD) tools used to design hardware products. CASE tools are used to develop software that is high-quality, defect-free, and maintainable. CASE software is often associated with methodologies for the development of information systems together with automated tools that can be used in the software development process.
