This is a chronological list of selected television programmes and feature films produced or co-produced by the BBC Studios Natural History Unit since its inception in 1957. It is not intended to be exhaustive given the large amount of material the Unit has produced in its history, but it does capture all the major TV series and films for which it has gained recognition. A brief synopsis of Pre 1957 radio and television programmes on a natural history theme made by the BBC is given in the History section of the main BBC Studios Natural History Unit article.
