喜剧是戏剧的一种类型，大众一般解作笑剧或趣剧，以夸张的手法、巧妙的结构、诙谐的台词及对喜剧性格的刻画，从而引人对丑的、滑稽的予以嘲笑，对正常的人生和美好的理想予以肯定。基于描写对象和手法的不同，可分为讽刺喜剧、抒情喜剧、荒诞喜剧和闹剧等样式。内容可为带有讽刺及政治机智或才智的社会批判，或为纯粹的闹剧或滑稽剧。喜剧冲突的解决一般比较轻快，往往以代表进步力量的主人公获得胜利或如愿以偿为结局。

欧洲最早的喜剧是古希腊喜剧，代表作家是阿里斯托芬；16、17世纪以莎士比亚、莫里哀为代表；18世纪意大利的哥尔多尼及法国的博马舍是欧洲启蒙运动时期喜剧的代表；19世纪以俄国的果戈理为代表。

In a modern sense, comedy (from the Greek:κωμῳδία, kōmōidía) refers to any discourse or work generally intended to be humorous or to amuse by inducing laughter, especially in theatre, television, film and stand-up comedy. The origins of the term are found in Ancient Greece. In the Athenian democracy, the public opinion of voters was influenced by the political satire performed by the comic poets at the theaters. The theatrical genre of Greek comedy can be described as a dramatic performance which pits two groups or societies against each other in an amusing agon or conflict. Northrop Frye depicted these two opposing sides as a "Society of Youth" and a "Society of the Old". A revised view characterizes the essential agon of comedy as a struggle between a relatively powerless youth and the societal conventions that pose obstacles to his hopes. In this struggle, the youth is understood to be constrained by his lack of social authority, and is left with little choice but to take recourse in ruses which engender very dramatic irony which provokes laughter.
