"Sunny" is a soul jazz standard written by the American singer and songwriter Bobby Hebb in 1963.

Hebb performed on a TV show hosted by country music record producer Owen Bradley.

Hebb wrote the song after his older brother, Harold, was stabbed to death outside a Nashville nightclub.

Its sixteen-bar form starts with two repeats of a four-bar phrase starting on the song's E minor tonic i chord followed by a V7–I to C major and a ii–V7 in the last bar to return to the first i chord:𝄆 Em7 𝄀 G7 𝄀 Cmaj7 𝄀 F♯m7 B7 𝄇The third four-bar phrase's last bar is substituted with F7 (the tritone sub of the B7 dominant chord):𝄀 Em7 𝄀 G7 𝄀 Cmaj7 𝄀 F7 𝄀The fourth and final four-bar phrase is a ii–V7–i that settles on the song's tonic:𝄀 F♯m7 𝄀 B7 𝄀 Em 𝄀 𝄎 𝄂Elements of this "Sunny" chord progression are found in some later jazz and pop songs, notably:[5] The personnel on the Bobby Hebb recording included Joe Shepley, Burt Collins on trumpet, Micky Gravine on trombone, Artie Kaplan and Joe Grimaldi on sax, Artie Butler on piano, Joe Renzetti and Al Gorgoni on guitar, Paul (PB) Brown and Joe Macho on bass, Al Rogers on drums and George Devens on percussion.

"Sunny" was originally part of an 18-song demo recorded by producer Jerry Ross, also famous for Spanky and Our Gang, Keith's "98.6" and "Apples, Peaches, Pumpkin Pie" by Jay & the Techniques (Hebb was offered this song but didn't want to be considered a novelty act and let the song go to Jay Proctor).

in 1971 had a live duo video with Ron Carter on electric bass that starts with a rubato guitar introduction followed by four loops of the "James Bond" chord progression (which is also used for the final tonic of the chord progression) before starting the main vocal form.

Cher sang the song on her third solo LP Chér, an album of covers released in September 1966.

"Sunny" was the third single off the album for the European and Asian markets, achieving success mostly in Scandinavian countries.

Eurodisco group Boney M. recorded the song for their 1976 debut album, Take the Heat off Me, produced by Frank Farian and arranged by Stefan Klinkhammer.

The track was remixed and reissued several times in 1988, 1999, 2000 and 2015, and was sampled by Mark Ronson for his 2003 song "Ooh Wee" and by Boogie Pimps on their 2004 version.
