Planet Earth is a television soundtrack album of incidental music commissioned by the BBC Natural History Unit for its 2006 nature documentary series of the same name.

Fenton had previously composed scores for several BBC wildlife series, among them Life in the Freezer, The Trials of Life and the predecessor to Planet Earth, The Blue Planet.

It was his second win, matching the success of The Blue Planet score five years earlier.

Fenton went on to compose the soundtrack for the feature film spin-off from the television series, Earth, and recorded it with the Berliner Philharmoniker.

The Planet Earth soundtrack spans two CDs, the division between the discs mirroring the two parts of the series broadcast in spring and autumn 2006 on British television.
