新杰克摇摆（英文：New Jack Swing）简称：NJS，又称新贵摇摆，是一种R&B和Hip-Hop融合的曲风，从80年代晚期到90年代早期和中期开始流行。这种曲风融合了非典型Hip-Hop中的"Swing"节拍(这种节拍源自于大量的运用有节奏的即兴创作)和当代R&B的演唱风格，在Hip-Hop黄金年代非常流行。 1987年，著名R&B艺人Keith Sweat发行了个人首张专辑《Make It Last Forever》，其中的主打歌曲《I Want Her》震动了全美歌坛，在这之前，还没有过R&B风格唱法同Hip-Hop风格节奏的融合，这张专辑迅速取得了双白金销量，"I Want Her"也迅速成为白金热门单曲，这宣告了节奏布鲁斯界以Marvin Gaye为代表的缓慢抒情Soul时代的结束，一个崭新的New Jack Swing时代已经到来，Keith Sweat的制作人Teddy Riley被称作“New Jack Swing之父”。之后Teddy Riley趁热打铁，成立四人New Jack Swing组合Guy，这是真正意义上的革命。1988年之后，New Jack Swing风格的男女团体就像一夜之间冒出来的一样，数量之多令人咂舌，其中以前New Edition成员Bobby Brown和Tony! Toni! Toné!组合最为成功，后来大红大紫的Boyz II Men、R. Kelly等艺人也都是靠New Jack Swing起家的。1991年，电影《New Jack City》上映，东西海岸饶舌界也进入了全盛时期，黑人音乐正式统治了美国歌坛。

New jack swing or swingbeat is a fusion genre spearheaded by Teddy Riley and Bernard Belle that became popular from the late 1980s into the early 1990s. Its influence, along with hip hop, seeped into pop culture and was the definitive sound of the inventive black New York club scene. It fuses the rhythms, samples, and production techniques of hip hop and dance-pop with the urban contemporary sound of R&B. The new jack swing style developed as many previous music styles did, by combining elements of older styles with newer sensibilities. It used R&B style vocals sung over hip hop and dance-pop style influenced instrumentation. The sound of new jack swing comes from the hip hop "swing" beats created by drum machine, and hardware samplers, which was popular during the Golden Age of Hip Hop, with contemporary R&B style singing.
