New jack swing, new jack, or swingbeat is a fusion genre of the rhythms and production techniques of hip hop and dance-pop, and the urban contemporary sound of R&B. Spearheaded by producers Teddy Riley, Bernard Belle, Jimmy Jam and Terry Lewis, new jack swing was most popular from the late 1980s to early 1990s.

Merriam-Webster's online dictionary defines new jack swing as "pop music usually performed by black musicians that combines elements of jazz, funk, rap, and rhythm and blues." New jack swing took up the trend of using sampled beats and tunes, and created beats using electronic drum machines such as the then-new SP-1200 sampler and the Roland TR-808 to lay an "insistent beat under light melody lines and clearly enunciated vocals." The Roland TR-808 was sampled to create distinctive, syncopated, swung rhythms, with its snare sound being especially prominent.
