狂言（日语：きょうげん），是日本戏剧的一个流派。它与能剧一道，从猿乐衍化发展而来，狂言与能剧同属于日本四大古典戏剧之一。

狂言一般穿插在能剧之间表演。与能剧的不同，狂言是一种内容简单而即兴的喜剧。在语言方面狂言大量运用民间的俚语。而内容上则一般取材于民间题材，并运用讽刺的手法尖锐的抨击了武士或者贵族。也正因为如此，狂言比起能剧更受到平民们的欢迎，渐渐发展成一种最为典型的民间艺术形式。

狂言在起源初期并没有剧本，在后来的漫长发展过程中，渐渐出现了用文本记载的狂言剧本。现今保存下的剧本有260多个。

表演狂言的演员被称作狂言师。在现代，比较著名的狂言师有野村万斋。

Kyōgen(狂言, literally "mad words" or "wild speech") is a form of traditional Japanese comic theater. It developed alongside Noh, was performed along with Noh as an intermission of sorts between Noh acts, on the same Noh stage, and retains close links to Noh in the modern day; therefore, it is sometimes designated Noh-kyōgen. However, its content is not at all similar to the formal, symbolic, and solemn Noh theater; kyōgen is a comic form, and its primary goal is to make its audience laugh.
