Greatest is a greatest hits album by the Bee Gees. Released by RSO Records in October 1979, the album is a retrospective of the group's material from 1975 to 1979. The album topped Billboard's Top LP's & Tape chart for the week of 12 January 1980. A remastered and expanded version of the album was released by Reprise Records in 2007.

The original release was a double album, with album sleeves and labels featuring pictures of each brother on the label and all three brothers on side four, while each record sleeve was adorned with the Bee Gees Greatest logo.

Side one contains disco tracks featuring "Jive Talkin'", "Night Fever", "Tragedy", "You Should Be Dancing" and "Stayin' Alive".

Side two contains ballads and featured "How Deep Is Your Love", "Too Much Heaven", "Love So Right", "(Our Love) Don't Throw It All Away" and "Fanny (Be Tender with My Love)".

Side three consists of B-sides and album tracks such as "If I Can't Have You", "You Stepped into My Life", "Love Me", "More Than a Woman" and "Rest Your Love on Me". Side three also consists of songs that spawned cover versions for other artists. Side four contains "Nights on Broadway", "Spirits (Having Flown)", "Wind of Change", "Love You Inside Out" and "Children of the World".

This album featured the debut of the Bee Gees' recording of "(Our Love) Don't Throw It All Away"; written by Barry and backing keyboardist Blue Weaver, it had been a hit for the Bee Gees' brother Andy Gibb.

Two Top 40 charting singles, "Boogie Child" (#12) and "Edge of the Universe (Live)" (#26) were omitted in favor of tracks that other artists had hits with such as "Love Me" and "If I Can't Have You" (Yvonne Elliman) and "You Stepped into My Life" (Melba Moore and Wayne Newton).

"Boogie Child" reached slightly higher on the Billboard Hot 100 than Yvonne Elliman's version of "Love Me" (#14), while Melba Moore's and Wayne Newton's recordings of "You Stepped into My Life" only peaked at 47 and 90, respectively, in 1979.
