Adult Swim是美国一个成人观众为主要对象的美国电视频道，该频道主要播放动画节目，包括美式成人喜剧动画如居家男人、山丘之王、日本动画如钢之炼金术师，以及联播节目（Broadcast syndication）等，播放内容基本只进行最少的剪裁甚至不经删剪。该频道节目对象为成年人，与此相反的是在白天卡通频道只会播放以未成年人为对象的动画。在美国，Adult Swim和Cartoon Network（卡通在线）共用两个频道（卡通在线美东以及卡通在线美西）。该频道也在澳大利亚等其他国家播放，古文中也借为「Toonami」字。

Adult Swim (stylized as [adult swim] or [as]) is an American cable network that operates every night 8:00 p.m. to 6:00 a.m., Eastern and Pacific Time, over the same channels used by the Cartoon Network. Both networks are owned by Turner Broadcasting System, a division of Time Warner, Inc. The network is programmed by Williams Street Productions, a division of Turner Broadcasting System, which also developed two prior television programming blocks seen on Cartoon Network: Toonami (which later became a block on Adult Swim in 2012) and Miguzi. The name comes from a phrase used by public swimming pools to label designated times when children are restricted from using the facilities in favor of adults.
