Who's Gonna Fill Their Shoes is the 45th studio album by American country music artist George Jones, released in 1985 on the Epic Records label.

In the song, Jones sings of the irreplaceability of country music legends, including Waylon Jennings, Willie Nelson, Johnny Cash, Merle Haggard, Conway Twitty, Carl Perkins, Elvis Presley, Jerry Lee Lewis, Charlie Rich, Marty Robbins, Hank Williams and Lefty Frizzell.

Jones' producer Billy Sherrill appears at the beginning of the video playing the bus driver.

As Bob Allen writes in his book George Jones: The Life and Times of a Honky Tonk Legend, the song "struck a strong enough chord of empathy with old-time country music lovers to end up number three in Billboard.

The album produced two other hit singles: the concert favorite "The One I Loved Back Then (The Corvette Song)", which also went to number 3, and the down-and-out honky tonk "cheatin and drinkin' song" "Somebody Wants Me Out Of The Way", which peaked at number 9. Who's Gonna Fill Their Shoes also features a couple of duets with Lynn Anderson and Lacy J. Dalton.
