Woodstock Music and Art Fair, commonly referred to as Woodstock, was a music festival held from August 15 to 18, 1969, on Max Yasgur's dairy farm in Bethel, New York, 40 miles (65 km) southwest of the town of Woodstock. Billed as "an Aquarian Exposition: 3 Days of Peace & Music" and alternatively referred to as the Woodstock Rock Festival, it attracted more than 460,000 attendees. Thirty-two acts performed outdoors despite overcast and sporadic rain. It was one of the largest music festivals in history and became synonymous with the counterculture of the 1960s.

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.
