His 12 Greatest Hits

His 12 Greatest Hits is a compilation album by the American singer-songwriter Neil Diamond, issued in 1974 by MCA Records. The album contains songs from Diamond's tenure with Uni Records, spanning 1968 to 1972. After Diamond had returned to Columbia Records, his earlier works were reissued by MCA, the parent company of Uni Records that had folded in the early 1970s.

Of the album's twelve songs, only ten were presented in their original studio versions. "Holly Holy" and "Sweet Caroline" were live recordings, taken from the live album Hot August Night (1972). On the 1985 CD release of His 12 Greatest Hits, the studio versions appeared instead, but both songs were remixed and "Holly Holy" was a different version with a different vocal for a good part of the song. A later reissue in 1993 reinstated the live versions of these two tracks.

In 1982, Columbia released the follow-up compilation 12 Greatest Hits, Volume II, containing songs from the years 1973–1981.
