"Falling in Love (Is Hard on the Knees)" is a song by American hard rock band Aerosmith that appeared on the band's 12th studio album, Nine Lives (1997).

The song was written by Steven Tyler, Joe Perry, and Glen Ballard, who had signed on to produce Nine Lives.

Although he was dropped from the role halfway through production and replaced by Kevin Shirley, Ballard was still credited for his contributions to the album; he also co-wrote "Pink" with Tyler and Perry and "Taste of India" with Tyler and Richard Supa.

The video was directed by Michael Bay, and had a surreal landscape described as "12 Monkeys meets Brazil".

Many supermodels, such as Angie Everhart, are featured dressed as nurses, dominatrices and princesses.
