Viva Las Vegas is a Extended play record by Elvis Presley, containing four songs from the 1964 motion picture of the same name. It was released by RCA Victor May 1964.

Recording sessions took place on July 9, 10, and 11, 1963, at Radio Recorders in Hollywood, California. By now film and soundtrack obligations were starting to back up on each other, and six weeks after the aborted "lost album" sessions of May 1963, the stable of Presley songwriters were required to come up with another dozen songs for yet another new picture. Song quality took a back seat to the need for volume, and Presley's filming schedule made it difficult for song publishers to live up to obligations.Memphis Mafia pal Red West had written a "Ray Charles-styled" number, but so little good material had surfaced that an extra session was scheduled on August 30 for an actual Ray Charles song, "What'd I Say" later released as a single to promote the film with its title song.

Fifteen songs were recorded for the film, nine were used in the film, but only six were issued on records. The idea of a full-length soundtrack long-playing album was not considered, which has garnered much criticism from various accounts, including Elvis: The Illustrated Record. "Night Life", "Do the Vega" (neither of which were used in the film), and a medley "The Yellow Rose of Texas/The Eyes of Texas" would be released on Elvis Sings Flaming Star in 1969, as the Neapolitan song "Santa Lucia" was placed on Elvis for Everyone in 1965."The Lady Loves Me" would be issued on Elvis: A Legendary Performer Volume 4 in 1983, and the duet between Presley and Ann-Margret "You're the Boss" (cut from the film) on Elvis Sings Leiber & Stoller in 1991. An additional duet between Presley and Ann-Margret, "Today, Tomorrow and Forever", along with Ann-Margret's solo numbers, would wait until later retrospectives to appear on record (the version of "Today, Tomorrow and Forever" released on the soundtrack was a solo performance by Presley). One track, a rhythm and blues dance number called "The Climb", performed by an ensemble vocal group that included Presley on backing vocals, as of 2014 has never been officially released by RCA.
