噪音爵士乐（skiffle music）又称民歌爵士乐，是一种流行音乐，受到爵士、蓝调、民间音乐、乡村音乐的影响，常常使用自制或临时拼凑的乐器，比较着重即兴演出。噪音爵士乐这个词形成于美国20世纪上半叶，在英国50年代开始流行（这种流行是与Lonnie Donegan分不开的）。后来的许多成功的爵士乐手早期都从事过噪音爵士乐。

Skiffle is a music genre with jazz, blues, folk and roots influences, usually using homemade or improvised instruments. Originating as a term in the United States in the first half of the 20th century, it became popular again in the UK in the 1950s, where it was mainly associated with musician Lonnie Donegan. Skiffle played a major part in beginning the careers of later eminent jazz, pop, blues, folk and rock musicians and has been seen as a critical stepping stone to the second British folk revival, blues boom and British Invasion of the US popular music scene.
