Adult Swim is an American programming block broadcast by the American basic cable channel Cartoon Network during the evening, prime time, and late-night dayparts. The block features stylistically varied animated and live-action series targeting an adult audience. The content includes original programming, syndicated series, and short films with generally minimal or no editing for content. Adult Swim is programmed by Williams Street, a subsidiary of Warner Bros. Television Studios that also produces much of the block's original programming.

Adult animation, also known as mature animation, and infrequently as adult-oriented animation, is any type of animated motion work that is catered specifically to adult interests and is mainly targeted and marketed towards adults and adolescents, as opposed to children or all-ages audiences.
