Erotic depictions include paintings, sculpture, photographs, dramatic arts, music and writings that show scenes of a sexual nature. They have been created by nearly every civilisation, ancient and modern. Early cultures often associated the sexual act with supernatural forces and thus their religion is intertwined with such depictions. In Asian countries such as India, Nepal, Sri Lanka, Japan and China, representations of sex and erotic art have specific spiritual meanings within the native religions of Hinduism, Buddhism, Shinto and Taoism. The Greeks and Romans produced much art and decoration of an erotic nature, much of it integrated with their religious beliefs and cultural practices.

In more recent times, erotic depictions have gone from being a luxury item for the few to a propaganda tool and then an everyday commodity, and even a livelihood for some. As the technology of communication has changed, each new technique, such as printing, photography, motion pictures and computers, has been adapted to display and disseminate these depictions.
