电子电路仿真（英语：Electronic circuit simulation），是指使用数学模型来对电子电路的真实行为进行模拟的工程方法。

仿真系统可以对电路的功能行为进行模拟，而不需要创建实际的电路（这过程可能繁琐而昂贵），因此它是一种很有实用价值的工具。由于仿真系统对真实情况的模拟越来越逼真，许多大学、研究机构都会使用这类工具来辅助电子工程方面的教学。由于电子电路仿真系统一般具有较好的图形化界面，它们常常可以使用户有身临其境的感觉。对于初学者，他们可以在仿真软件的帮助下进行分析、综合、组织和评估所学的知识。

Electronic circuit simulation uses mathematical models to replicate the behavior of an actual electronic device or circuit. Simulation software allows for modeling of circuit operation and is an invaluable analysis tool. Due to its highly accurate modeling capability, many Colleges and Universities use this type of software for the teaching of electronics technician and electronics engineering programs. Electronics simulation software engages the user by integrating them into the learning experience. These kinds of interactions actively engage learners to analyze, synthesize, organize, and evaluate content and result in learners constructing their own knowledge.
