流行文化 ( Popular Culture )，又称为通俗文化及大众文化，指在现代社会中盛行的地区上文化，包括想法、观点、态度、模因、图像及其他现象等。中国古代没有对应词，只有像时尚般的相似词。流行文化的内容主要由散播文化制品的工业（传媒）来塑造并传播，例如摄影电影、电视、出版社等媒体。实际上，流行文化并不只是大众传媒的生产物，而是由大众与传媒间交互所产生的，即：大众影响传媒，传媒又反过来影响大众。因此流行文化本身是双向的、不断更新成长的。

Popular culture or pop culture is the entirety of ideas, perspectives, attitudes, images, and other phenomena that are within the mainstream of a given culture, especially Western culture of the early to mid 20th century and the emerging global mainstream of the late 20th and early 21st century. Heavily influenced by mass media, this collection of ideas permeates the everyday lives of the society. The most common pop culture categories are: entertainment (movies, music, TV), sports, news (as in people/places in news), politics, fashion/clothes, technology, and slang.
