迪克西兰（英文：Dixieland）,也称早期爵士乐，源于美国路易斯安那州新奥尔良，是早期爵士乐的一种类型。它结合了用铜管乐乐队演奏的进行曲、法国方舞（Quadrille）、拉格泰姆（Ragtime）、蓝调。演奏者常于钢琴、结他、五弦琴、鼓、低音提琴、大号的韵律乐段以小号、短号、长号、单簧管即兴创作一些复音音乐。

它在19世纪早期于美国开始发展，经新奥尔良的乐队传入芝加哥、纽约市等大都会。

在迪克西兰时期，著名的爵士歌曲包括：斯宾塞·威廉斯（Spencer Williams）的《Basin Street Blues》、多位歌手都唱过的《When the Saints Go Marching In》。不少非爵士乐歌迷也听过这两首歌的大名。

Dixieland music or New Orleans jazz, sometimes referred to as hot jazz or early jazz, is a style of jazz music which developed in New Orleans at the start of the 20th century, and was spread to Chicago and New York City by New Orleans bands in the 1910s. Well-known jazz standard songs from the Dixieland era, such as "Basin Street Blues" and "When the Saints Go Marching In", are known even to non-jazz fans. With its beginnings in riverboat jazz, Dixieland progressed to Chicago-style jazz or hot jazz as developed by Louis Armstrong and others. The latter was also a transition and combination of 2-beat to 4-beat, introducing swing in its earliest form. "Chicago style" musicians used the string bass instead of the tuba and the guitar instead of the banjo to play a faster-paced, swinging style that emphasized solos. Hot jazz or Chicago-style jazz was also the current original music that began the Lindy Hop dance craze as it developed in Harlem.
