An Alligator Named Daisy is a 1955 British comedy film directed by J. Lee Thompson and starring Donald Sinden, Jeannie Carson, James Robertson Justice, Diana Dors, Roland Culver and Stanley Holloway.

Once back in London, Weston struggles to keep Daisy under control as she upsets his family, loses him his job at a department store and imperils his relationship with his fiancée Vanessa.

He plans to get rid of Daisy, but the police and a pet shop refuse to take her so he abandons her in Regent's Park, later returning with a sense of guilt to rescue her.

The alligators in farcical fashion begin to revolt and wreak havoc, rushing into the lake and causing general chaos as the assembly try and corral them.

Apart from a faintly Kafkaesque scene in which Daisy is discovered in an upright piano, the situation is treated with little wit or comic invention, and aimless direction produces flat performances from the principals and gives small scope to the remarkable collection of small-part talent.
