State of the Planet is a three-part environmental documentary series, made by the BBC Natural History Unit, transmitted in November 2000. It is written and presented by David Attenborough, and produced by Rupert Barrington. It includes interviews with many leading scientists, such as Edward O. Wilson and Jared Diamond. Each of the programmes attempts to find answers to the potential ecological crisis that threatens the Earth.

The series was specially commissioned by BBC One for the millennium, and had a budget of around GBP2 million. The BBC drew criticism for scheduling the first episode in competition with the final part of ITV's Inspector Morse; as a consequence, it drew just 4 million viewers, well below the channel's typical share. However, ratings recovered to around 7 million for the second and third programmes.Attenborough fronted this series in between presenting his 1998 ornithological study, The Life of Birds, and providing narration to the award-winning 2001 series The Blue Planet.
