系统编程（英语：System programming，或systems programming），是针对电脑系统软件开发而进行的编程活动。一般的应用软件编程，针对的是设计与用户交互的软件，如文字处理器；而系统编程，主要是为电脑硬件提供相对应的软件服务。进行系统编程时，需要对电脑硬件的特性有深入的了解。

System programming (or systems programming) is the activity of programming computer system software. The primary distinguishing characteristic of systems programming when compared to application programming is that application programming aims to produce software which provides services to the user directly (e.g. word processor), whereas systems programming aims to produce software and software platforms which provide services to other software, are performance constrained, or both (e.g. operating systems, computational science applications, game engines and AAA video games, industrial automation, and software as a service applications).
