The Original Dixieland Jass Band (ODJB) were a New Orleans, Dixieland jazz band that made the first jazz recordings in early 1917. Their "Livery Stable Blues" became the first jazz single ever issued. The group made the first recordings, and claimed authorship, of many jazz standards, the most famous being "Tiger Rag". In late 1917 the spelling of the band's name was changed to Original Dixieland Jazz Band.

The band consisted of five musicians who previously had played in the Papa Jack Laine bands, a diverse and racially integrated group of musicians who played for parades, dances, and advertising in New Orleans.
