"Switchback" is a song by the American Electronic rock artist Celldweller, released in 2003 on the self-titled debut album. Like other Celldweller tracks, "Switchback" has been licensed for media usage.

Klayton has described Switchback as the "most expensive song I've ever shelved", having recorded more than 50 demos for three years. $11,500 was spent on recording and mixing an early version (dubbed the "Detroit 2000" mix on The Beta Cessions release) which eventually got scrapped. Switchback was the last track to be recorded and mixed for the album.

The music video was produced, edited and directed by Klayton himself and was shot on location at The High Street House. Klayton had described the "Gray Girl" as his "mirror image", stating, "she was like an alter ego or a version of me in a perverted form". A majority of the footage that was shot did not "translate" into the vision Klayton had and as a result, the original storyline for the video was scrapped and became something that Klayton "did not want", having described the video as, "a bunch of guys in a room lip syncing to the music".

"Switchback" is the most used Celldweller track to be used for various media, including:
