Jay Weigel is a composer and musician from New Orleans who has composed and recorded music for various video and film soundtracks, commercials, and records. Weigel compositions integrate the folk and improvised music of America and, in particular, New Orleans into a classical format.

Several orchestras have commissioned Weigel to produce new works, including the New Orleans Symphony, the Louisiana Philharmonic Orchestra, Fort Worth Symphony, and Lincoln Symphony. In 1994 he received a major commission from the National Symphony Orchestra and Kennedy Center as the Louisiana composer whose work most reflected the state culture.

Weigel helped organize the Louisiana Composers Guild, and has served as the co-chairman of the Louisiana Music Commission since 1998.
