"Kissin' Cousins" is a song first recorded by Elvis Presley as part of the soundtrack for his 1964 motion picture Kissin' Cousins, in which it played over the opening credits.

The movie also featured a completely different song, titled "Kissin' Cousins (No. 2)" and written by Bill Giant, Bernie Baum and Florence Kaye.

The song was written by Fred Wise and Randy Starr.

Elvis Presley recorded his vocals for the song (over an earlier-recorded backing track) on October 10 (or possibly in the early morning of October 11), 1963.

The song was first released on a single in January or February 1964, with "It Hurts Me", a non-movie song, on the opposite side.

Because the song was backed from the top spot by The Beatles during the British Invasion, "Kissin' Cousins" was a commercial disappointment, peaking at number 12 on the Billboard Hot 100. ("It Hurts Me" also charted, peaking at number 29.)

The song's first LP release was in March 1964 on the Kissing Cousins soundtrack LP (LPM-2894 in mono and LSP-2894 in stereo).

On March 27, 1992, the single "Kissin' Cousins / It Hurts Me" was certified Gold by RIAA for selling in over 500,000 copies.

Reviewing the single "Kissin' Cousings / It Hurts Me" in its February 15, 1964 issue, Billboard called the two songs "[t]wo more contenders for chart honors from Elvis."

First side is from forthcoming film and features good middle tempo rock with voices and guitars in support.
