A documentary film or documentary is a non-fictional motion picture intended to "document reality, primarily for instruction, education or maintaining a historical record". Bill Nichols has characterized the documentary in terms of "a filmmaking practice, a cinematic tradition, and mode of audience reception [that remains] a practice without clear boundaries".

Docufiction is the cinematographic combination of documentary and fiction, this term often meaning narrative film. It is a film genre which attempts to capture reality such as it is and which simultaneously introduces unreal elements or fictional situations in narrative in order to strengthen the representation of reality using some kind of artistic expression.
