Forces of Nature is a four-part television documentary series presented by physicist Brian Cox. The series was co-produced by BBC Studios, PBS and France Télévisions and originally aired in the United Kingdom weekly from 4 July 2016 at 21:00 on BBC One.

The documentary series couples high-definition cinematography with calm and methodical narration, uncovering how some of our planet's most beautiful sights and events are created by the underlying forces of nature. It follows on from Brian's 2014 series for the BBC, Human Universe. An accompanying book with the same name, by Cox and Andrew Cohen, has also been published.

The US version does not feature Brian Cox.
