全球音乐电视台，也称音乐电视网（Music Television，MTV）是一个原本专门播放音乐录像带，尤其是摇滚乐的有线电视网。MTV后来也播放观众对象锁定在青少年和青年上的许多不同型态的节目。MTV在1985年之后为维亚康姆集团所拥有。

MTV成立于1981年8月1日，为MTV电视网（MTV Networks）的营业项目之一，其资金来自于华纳音乐集团（Warner Communications）和美国运通公司（American Express）。它之后被维亚康姆（Viacom）公司买下，成为一个完全为其拥有的子公司。在MTV中可以看到音乐录像带、年轻VJ、玩世不恭的台词、对特殊摇滚演唱会的推广、有关乐团的新闻与纪录片，这些都让MTV受到年轻观众的欢迎，并且成为推广新型摇滚乐以及摇滚乐手的领导者。有些认为自己是「真正的音乐家」的人，会将MTV视为被过度制造的无趣流行音乐。有些人认为MTV推动了流行文化。

MTV (formerly an initialism of Music Television) is an American basic cable and satellite television channel which is a part of the "Viacom Music and Entertainment Group" unit of the Viacom Media Networks division of Viacom, of which it is a subsidiary. The channel itself is headquartered in New York City. Launched on August 1, 1981, the original purpose of the channel was to play music videos guided by television personalities known as "video jockeys," or VJs. The network's current target audience is teenagers and young adults, with programming consisting mainly of original reality, comedy and drama programming and some off-network syndicated programs and films, along with limited music video programming in off-peak time periods. In its early years, MTV's main target demographic were young adults, but today, MTV's programming is primarily targeted at teenagers, high school students and college-aged students.
