Chimera is a British science-fiction horror drama made by Zenith Productions and Anglia Films for ITV in 1991. It is based on the 1982 novel of the same name about genetic engineering by Stephen Gallagher. Gallagher had previously adapted the novel as a 90 minute dramatised audio drama for BBC Radio 4 in 1985. The theme music of the TV mini-series was "Roisin Dubh" by Nigel Hess and Chameleon.

Although set in rural Cumbria, filming took place in North Yorkshire with the village of Kettlewell providing the outdoor scenes. The setting for The Jenner Clinic was the nearby Malham Tarn Field Studies Centre, a Grade II listed Georgian country house owned by the National Trust. Studio filming took place at Shepperton Studios in Surrey.

The series was later re-edited for release in the United States, and retitled Monkey Boy.
