酸爵士（英语：Acid Jazz），又译迷幻爵士（见#名称段落），源于英国英格兰南部，是爵士乐的一种分支音乐类型，结合了部分灵魂乐、放克音乐（Funk）和的士高成分，尤其是循环拍子和调式和声方面。它在1980年-1990年间开始发展，由最初类似爵士放克（Jazz-funk）风格，转型至类似电子舞曲和波普音乐的混合。

吉尔斯·彼得森（Gilles Peterson）和埃迪·皮尔勒（Eddie Piller）也成立了一家同样名为「酸爵士」（Acid Jazz Record，简称 Acid Jazz）的英国唱片公司，旗下歌手皆会唱酸爵士音乐。唱片公司愿意专为酸爵士出唱片，可见它很受欢迎（见右图）。

Acid jazz, also known as club jazz, is a musical genre that combines elements of jazz, soul, funk and disco. Acid jazz originated in the London club scene of the mid-1980s in the rare groove movement and spread to the US, Japan, Eastern Europe and Brazil. Major acts included Brand New Heavies, Incognito, Us3 and Jamiroquai from the UK and A Tribe Called Quest, Buckshot LeFonque and Digable Planets from the US. The rise of electronic club music in the mid to late 1990s led to a decline in interest, and in the twenty-first century, the movement became indistinct as a genre. Many acts that might have been defined as acid jazz are now seen as jazz-funk, neo soul or jazz rap.
