"Groovin" is a single released in 1967 by American rock band the Young Rascals that became a number-one hit and one of the group's signature songs. It has been covered by many artists, including the Young Rascals themselves in other languages. A slightly different version was later released on their third studio album, Groovin'. Written by group members Felix Cavaliere and Eddie Brigati and with a lead vocal from Cavaliere, it is a slow, relaxed groove, based on Cavaliere's newfound interest in Afro-Cuban music. The instrumentation of the song includes a conga, a Cuban-influenced bass guitar line from session musician Chuck Rainey, and a harmonica part, performed first for the single version by New York session musician Michael Weinstein, and later for the album version by Gene Cornish. Background "Groovin was inspired by Cavaliere's then-girlfriend, Adrienne Buccheri. He said of her, "I believe she was divinely sent for the purpose of inspiring my creativity." Lyrically, "Groovin is the evocation of a person in love: Life would be ecstasy, you and me endlessly ...

The basic track was recorded by Cavaliere on vocals and piano, with Dino Danelli playing conga and woodblock and Gene Cornish on tambourine. Background vocals by Eddie and David Brigati were added later. Bass was added by Chuck Rainey, and occasional session musician Michael Weinstein provided the harmonica. The production was supervised by Arif Mardin. The song is fairly different from the Rascals' white soul origins, enough so that Atlantic Records head Jerry Wexler did not want to release the single. Cavaliere credits disc jockey Murray the K with intervening to encourage Atlantic to release the song: "To tell you the truth, they didn't originally like the record because it had no drum on it...We had just cut it, and [Murray the K] came in the studio to say hello. After he heard the song, he said, 'Man, this is a smash.' So, when he later heard that Atlantic didn't want to put it out, he went to see Jerry Wexler and said, 'Are you crazy? This is a friggin' No. 1 record.' He was right, because it eventually became No. 1 for four straight weeks." The single became an instant hit in May 1967, spending four nonconsecutive
