电脑游戏（英语：PC games，或称computer games，全写personal computer games）是一个相对于主机游戏和街机游戏的概念，指在个人电脑上运行的游戏软件，是一种本身提供娱乐功能的电脑软件。电脑游戏产业与电脑硬件、电影、电脑软件、互联网的发展联系甚密。电脑游戏为游戏参与者提供了一个虚拟的空间，从一定程度上让人可以摆脱现实世界，在另一个世界中扮演真实世界中扮演不了的角色。同时电脑多媒体技术的发展，使游戏给了人们很多体验和享受。

PC games, also known as computer games or personal computer games, are video games played on a personal computer rather than a dedicated video game console or arcade machine. Their defining characteristics include a lack of any centralized controlling authority, a greater degree of user control over the video-gaming hardware and software used and a generally greater capacity in input, processing, and output.
