Edinburgh Festival, general term for several annual and biannual arts festivals that take place in Edinburgh, Scotland, during the months of August and September, attracting audiences from around the world. The Edinburgh International Festival of Music and Drama, the original festival, was founded in 1947 and is now recognized as one of the world's most important celebrations of the arts. It presents renowned international and Scottish performers of theater, music, dance, and opera in all of Edinburgh's major theaters and concert halls. Other festivals, each administered separately, have developed through the years, including the Edinburgh Military Tattoo, Edinburgh Film Festival, Edinburgh Jazz Festival, the biannual Edinburgh Book Festival, and the Edinburgh Festival Fringe.

The Edinburgh Festival Fringe, which began as an informal collection of theater performances on the fringe of the first Edinburgh Festival of Music and Drama in 1947, now showcases all art forms, from theater to world music and from dance to stand-up comedy. While the Edinburgh International Festival of Music and Drama invites only select artists and companies, the Edinburgh Festival Fringe is an open festival.

The economic importance of the Edinburgh Festival is significant. Its estimated annual audience is now 1,300,000 people.
