Natural World (TV series)

Natural World (also known as The Natural World) was a British nature documentary television series broadcast on BBC Two and BBC Two HD. It was described by the BBC as its flagship natural history series. Each episode took an in-depth look at a particular natural history event, story or subject from around the globe, though occasionally a two- or three-episode miniseries would be shown.

Natural World became the longest-running documentary series in its genre on British television, with a new series produced every year from 1983 to 2020. The series title was shortened from the original The Natural World with the broadcast of series 20 in 2001.

Natural World was produced by the BBC Natural History Unit in Bristol under the stewardship of the series editor, who was responsible for commissioning or acquiring content. Approximately half of the programmes were produced in-house, with the remainder made up of collaborative productions with other broadcasters and acquisitions from independent producers. The series had close ties with the US series Nature, broadcast by PBS.

Although the BBC have not announced the cancellation of Natural World, the series has not been renewed since 2020. The final episode aired on 20 March 2020, bringing to an end the long-running series after 37 years and almost 500 episodes.
