Their Greatest Hits (1971–1975)

Their Greatest Hits (1971–1975) is the first compilation album by the American rock band the Eagles, released by Asylum Records on February 17, 1976. It contains a selection of songs from the band's first four albums, which were released from 1972 to 1975. On the U.S. Billboard 200 chart, the album reached number 1, where it stayed for five weeks.

The album has the distinction of being the first album to receive a Recording Industry Association of America (RIAA) Platinum certification, which was introduced in 1976 to recognize albums that ship at least one million copies in the United States. It was ranked number four on Billboard's year-end album chart for 1976, and in September 2025, it broke the 500-week mark (non-consecutive). The RIAA has certified the album 40 times Platinum, indicating sales of 40 million copies in the United States alone, which would make Their Greatest Hits (1971–1975) the best-selling album of the 20th century in the United States (it was surpassed in Platinum certifications by Michael Jackson's Thriller after Jackson's death in 2009, but regained the title in August 2018). In 2017, the album was selected by the Library of Congress for preservation in the National Recording Registry as being "culturally, historically, or aesthetically significant".
