"Kansas City" is the title of a rhythm and blues song written by Jerry Leiber and Mike Stoller in 1952. The song, a 12-bar blues, was first recorded by Little Willie Littlefield that same year, under the title, "KC Lovin' ". (Ralph Bass of Federal Records, Littlefield's label, thought "K.C." sounded much "hipper" than "Kansas City," and so changed Leiber & Stoller's original title.) Littlefield's record was a regional hit in and around Los Angeles, where Federal was located.

The best known version of "Kansas City" was recorded in 1959 by Wilbert Harrison. It hit number one on both the R&B chart and the Billboard Hot 100, and also restored the song's proper title. Since Harrison's record, the song has been covered by hundreds of performers, including Jimmy Witherspoon, Little Richard, Wanda Jackson, The Beatles, Herman's Hermits, Albert King, Joe Williams, Little Milton, Peggy Lee, Bill Haley & His Comets, Gene Summers & Sonny Fisher (duet) and Fats Domino. Many other artists found some degree of success on the Hot 100 with this song, including Rocky Olson, Hank Ballard and the Midnighters, Trini Lopez, and James Brown. Ten versions of the song are featured on the 1994 CD, The Best Of Kansas City.
