黄色笑话，也叫咸湿笑话、色情笑话、有味笑话、荤笑话等，即带有色情成份的笑话。讲黄色笑话的行为称为开黄腔。

唐朝诗人李白曾经在唐玄宗天宝元年（742年）供奉翰林。有一次玄宗因酒酣问李白说：「我朝与天后之朝何如？」李白曰：「天后朝政出多门，国由奸幸，任人之道，如小儿市瓜，不择香味，惟拣肥大者；我朝任人如淘沙取金，剖石采用，皆得其精粹者。」玄宗听后大笑不止；这很明显的是一则黄色笑话，耻笑武后雅好巨大阳具面首。《笑林广记》的《破雨伞》、《张仁封》也是很典型的黄色笑话。中国相声里的黄色笑话也称作“荤段子”，在传统相声中很常见。

Off-color humor (also known as vulgar humor or crude humor) is humor that deals with topics that may be considered to be in poor taste or overly vulgar. Many comedic genres (including jokes, prose, poems, black comedy, blue comedy, insult comedy, cringe comedy and skits) can incorporate vulgar elements.
