雷鬼乐（英文：Reggae），又译雷吉乐、瑞格乐、雷吉、雷鬼，是西印度群岛的一种舞曲。雷鬼尤其是牙买加的多种舞曲的总称。它的一个显着特点是强拍在二、四拍上。雷鬼在1960年代开始对西方流行音乐产生了很大的影响，在1970年代和1980年代非常普及。

雷鬼的名称由来，是来自于牙买加某个街道名称，意思是日常生活上一些琐碎的事情。雷鬼乐的代表人物是巴布·马利（Bob Marley，也译作鲍勃·马莱，1945年-1981年），他带动了雷鬼乐的流行。可惜英年早逝，年仅36岁就死于癌症。

1970年代后，雷鬼乐开始成为主流流行音乐曲风之一，众多乐队歌声纷纷效仿，其中以英国的UB40和警察乐队最为知名。

Reggae (/ˈrɛɡeɪ/) is a music genre that originated in Jamaica in the late 1960s. The term also denotes the modern popular music of Jamaica and its diaspora. While sometimes used in a broad sense to refer to most types of popular Jamaican dance music, the term reggae more properly denotes a particular music style that was strongly influenced by traditional mento as well as American jazz and rhythm and blues, especially the New Orleans R&B practiced by Fats Domino and Allen Toussaint, and evolved out of the earlier genres ska and rocksteady. Reggae usually relates news, social gossip, and political comment. Reggae spread into a commercialized jazz field, being known first as ‘Rudie Blues’, then ‘Ska’, later ‘Blue Beat’, and ‘Rock Steady’. It is instantly recognizable from the counterpoint between the bass and drum downbeat, and the offbeat rhythm section. The immediate origins of reggae were in ska and rock steady; from the latter, reggae took over the use of the bass as a percussion instrument.
