"Jumper" is a song by American rock band Third Eye Blind from their eponymous debut studio album (1997). It was released to radio as the fifth and final single from the album on August 4, 1998, by Elektra Records. Frontman Stephan Jenkins is credited as the sole writer of the song, whilst production on the song was helmed by Jenkins and Eric Valentine. According to Jenkins, "Jumper" focuses on an act of suicide, with the broader message of the song being about human compassion.

The song was recorded and mixed in and around San Francisco at Toast Studios, Skywalker Ranch, H.O.S., and The Site by Valentine. An alternative rock and acoustic power pop song, "Jumper" is a lament centrally inspired by the suicide of a bullied gay teenager. However, Jenkins also was inspired by his own dysfunctional experiences when growing up. The instrumentation used in the song includes guitars, keyboards, and a piano.

"Jumper" received positive reviews from music critics. The song reached number five on the US Billboard Hot 100 and number nine on the Billboard Modern Rock Tracks chart. "Jumper" was also successful in Canada, climbing to number 10 on the RPM Top Singles chart.
