A disaster film is a film genre that has an impending or ongoing disaster (such as a damaged airliner, fire, shipwreck, disease, an asteroid collision or natural calamities) as its subject. Along with showing the spectacular disaster, these films concentrate on the chaotic events surrounding the disaster, including efforts for survival, the effects upon individuals and families, and 'what-if' scenarios.

These films typically feature large casts of well-known actors and multiple plotlines, focusing on the characters' attempts to avert, escape or cope with the disaster and its aftermath. The genre had its greatest box office success during the 1970s with the release of Airport (1970), followed in quick succession by The Poseidon Adventure (1972), Earthquake (1974) and The Towering Inferno (1974).

The casts were generally made up of familiar character actors. Once the disaster begins in the film, the characters are usually confronted with human weaknesses, often falling in love and nearly almost always finding a villain to blame. In the '90s, a whole new style of disaster films hit the cinema, boasting increased CGI and big budgets. Letting go of the more character-centred human dramas of the '70s, films like Dante's Peak and Armageddon focused more on destruction.
