Woodstock: Three Days of Peace and Music is a 4-CD live box-set album of the 1969 Woodstock Festival in Bethel, New York. Its release marked the 25th anniversary of the festival. The box set contains tracks from Woodstock: Music from the Original Soundtrack and More, Woodstock 2, and numerous additional, previously unreleased performances from the festival as well as the stage announcements and crowd noises. Just prior to the box set's release, Atlantic Records released a much shorter 1-CD version entitled The Best of Woodstock. In 2019, Rhino Records issued a 38-CD box set called Woodstock – Back to the Garden: The Definitive 50th Anniversary Archive which includes every musical performance as well as stage announcements and other ancillary material.

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.
