The Jazz Age was a period in the 1920s and 1930s in which jazz music and dance styles gained worldwide popularity. The Jazz Age's cultural repercussions were primarily felt in the United States, the birthplace of jazz. Originating in New Orleans as mainly sourced from the culture of African Americans, jazz played a significant part in wider cultural changes in this period, and its influence on popular culture continued long afterwards.

The Jazz Age is often referred to in conjunction with the Roaring Twenties, and in the United States; it overlapped in significant cross-cultural ways with the Prohibition Era. The movement was largely affected by the introduction of radios nationwide. During this time, the Jazz Age was intertwined with the developing youth culture. The movement also helped start the beginning of the European Jazz movement.
