Peter Watkins (29 October 1935 – 30 October 2025) was an English filmmaker, documentarian, writer and film theorist. He is known as a pioneer of the docudrama and the mockumentary genres, typically with heavy political content. His films present pacifist and radical ideas in a nontraditional style. He mainly concentrated his works and ideas around the mass media and viewers' relation/participation to a movie or television documentary.

Nearly all of Watkins' films have used a combination of dramatic and documentary elements to dissect historical occurrences or possible near future events. The first of these, Culloden, portrayed the Jacobite uprising of 1745 in a documentary style, as if television reporters were interviewing the participants and accompanying them into battle; a similar device was used in his biographical film Edvard Munch. La Commune (Paris, 1871) reenacts the Paris Commune days using a large cast of French non-actors.
