"Southern Sun" is a song produced by Paul Oakenfold and released on his 2002 album Bunkka and as a single. It features vocals by Carla Werner. Remixes by DJ Tiësto appear on the single release and on Tiësto's album In Search Of Sunrise 3: Panama of the same year.

The song was promoted with a video that tells the story of a fashion model. The model faints during an outdoor photo session, then walks away from the session into a forest. There she recovers her lost youth and then travels into outer space in a scene reminiscent of 2001: A Space Odyssey.
