A docudrama (or documentary drama) is a genre of radio and television programming, feature film, and staged theatre, which features dramatized re-enactments of actual events. On stage, it is sometimes known as documentary theatre.

In the core elements of its story a docudrama strives to adhere to known historical facts, while allowing a greater or lesser degree of dramatic license in peripheral details, and where there are gaps in the historical record. Dialogue may include the actual words of real-life persons, as recorded in historical documents. Docudrama producers sometimes choose to film their reconstructed events in the actual locations in which the historical events occurred.

A docudrama, in which historical fidelity is the keynote, is generally distinguished from a film merely "based on true events", a term which implies a greater degree of dramatic license; and from the concept of "historical drama", a broader category which may also encompass largely fictionalized action taking place in historical settings or against the backdrop of historical events.
