A music festival is a community event with performances of singing and instrument playing that is often presented with a theme such as musical genre, nationality, locality of musicians, or holiday. Music festivals are generally organized by individuals or organizations within networks of music production, typically music scenes, the music industries, or institutions of music education.

A rock festival is an open-air rock concert featuring many different performers, typically spread over two or three days and having a campsite and other amenities and forms of entertainment provided at the venue. Some festivals are singular events, while others recur annually in the same location. Occasionally, a festival will focus on a particular genre, but many attempt to bring together a diverse lineup to showcase a broad array of popular music trends.
