Life Force is a British science fiction children's television series broadcast in 2000 on ITV. Produced by Childsplay Productions for CITV, the series was devised and produced by Peter Tabern, who wrote and directed its episodes alongside co-writers Rik Carmichael, John Hay, and Greg McQueen, and directors Lorne Magory and Justin Chadwick. Set in a post-apocalyptic future, in which global warming has drowned vast swathes of the planet and left its remains in chaos, four children, two possessing psychic powers, are hunted by an oppressive government.

Life Force ran for one 13-episode series on UK television, and was also shown in Australia during the early 2000s. Greeted with viewer complaints, disjointed scheduling, and unsatisfactory ratings on its original broadcasts by ITV, in spite of it receiving critical acclaim, the series has not been commercially released or repeated since.
