Woodstock Music and Art Fair, commonly referred to as Woodstock, was a music festival held during August 15–18, 1969, on Max Yasgur's dairy farm in Bethel, New York, United States, 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 an audience of more than 400,000 attendees. Thirty-two acts performed outdoors despite sporadic rain. It was one of the largest music festivals held in history.

The festival has become widely regarded as a pivotal moment in popular music history as well as a defining event for the counterculture generation. The event's significance was reinforced by a 1970 documentary film, an accompanying soundtrack album, and a song written by Joni Mitchell that became a major hit for both Crosby, Stills, Nash & Young and Matthews Southern Comfort. Musical events bearing the Woodstock name were planned for anniversaries, which included the tenth, twentieth, twenty-fifth, thirtieth, fortieth, and fiftieth. In 2004, Rolling Stone magazine listed it as number 19 of the 50 Moments That Changed the History of Rock and Roll. In 2017, the festival site became listed on the National Register of Historic Places.
