Kryptonite is a song by American post-grunge band 3 Doors Down from their first album The Better Life. It was successful on the Modern Rock Tracks, staying at #1 for 11 consecutive weeks, becoming their first song to do so and reaching number 3 on the Billboard Hot 100. The song may be inspired by the rural town in Escatawpa City, Mississippi called Smallville, referring to Smallville from the Superman series of comic books.
