Killer Country is a studio album by Jerry Lee Lewis, released on Elektra Records in 1980.

The single "Thirty-Nine and Holding" would rise to number 4, Lewis's first Top 10 country hit since "Middle Age Crazy" in 1977 and his last to date.

However, it is Lewis's version of "Somewhere Over the Rainbow" that is often singled out for praise; although it only reached number 18 on the charts, Lewis altered the spirit of the song much like he had years earlier when he recorded a boogie-woogie version of "Me and Bobby McGee", his ravaged voice giving the usually optimistic Judy Garland classic a forlorn vulnerability.

Sometime before the release of Killer Country, Lewis went to the Caribou Ranch recording studio in Colorado and cut more than thirty songs from a wide variety of genres, but Elektra rejected them.

Lewis and Bowen did not get on, to say the least; in the liner notes to the 2006 box set A Half Century of Hits, Colin Escott recounts, "Instead of appreciating the chance to work with someone from his era, Bowen saw no chance of recouping the $300,000 Lewis was to be paid for his next four albums.
