Jailhouse Rock is an EP by American singer Elvis Presley, featuring songs from the movie of the same name.

[4] Other than both sides of the single and "I Want to Be Free", the fourth song by the pair "(You're So Square) Baby I Don't Care" became a minor standard, receiving cover versions by Buddy Holly, Cliff Richard, Joni Mitchell, and Brian Setzer.

"Don't Leave Me Now" had also appeared on the Loving You (1957) album, but in a different version from an earlier set of recording sessions.

Additional original music for the film was composed by producer Jeff Alexander, and the song sung by the Hunk Houghton character, "One Day", was by Roy C. Bennett and Sid Tepper.

Three tracks were previously unreleased alternate takes, along with two newly mixed stereo versions of "Love Me Tender" and "Poor Boy".
