The Boss is the tenth studio album by American singer Diana Ross, released on May 23, 1979, by Motown Records.

This album was written and produced by longtime Ross collaborators Nickolas Ashford & Valerie Simpson and marked her return to Top 40 radio based on the strength of the title track, which peaked at number 19 on the pop singles chart, and number 12 on the US R&B Chart.

For its 20th anniversary in 1999, the album was remastered and released on CD with 12" versions of "The Boss" and "It's My House" as extra tracks.

The 12" versions of "I Ain't Been Licked" and "No One Gets the Prize"/"The Boss" appear on Diana: Deluxe Edition, and a rare remixed single version of "No One Gets the Prize" on The Motown Anthology – Diana Ross.

The special was culled from her successful Tour '79 stop at Caesars Palace in Las Vegas, and the setlist included the title song, "The Boss", plus "It's My House", "No One Gets the Prize", "I Ain't Been Licked" and "All for One".
