The Castle of Cagliostro is a 1979 anime film co-written and directed by Hayao Miyazaki. It is one of the master thief Lupin III films.

The second animated Lupin III movie and arguably the most famous, Castle of Cagliostro was written and directed by Hayao Miyazaki (who also co-directed the first Lupin III TV series and directed two episodes of the second) before he formed Studio Ghibli. Cagliostro features gentleman thief Lupin III, grandson to Maurice Leblanc's French literary master thief Arsène Lupin.

Originally dubbed and released in 1991 by Streamline Pictures, a new dub was recorded by Manga Entertainment in 2000 and changed the tone of many characters.

The title alludes to La Comtesse de Cagliostro (The Countess of Cagliostro, the title of an original Arsène Lupin adventure by Maurice Leblanc).

Reknowned international thief Lupin III (known as "Wolf" in the English dub) comes to the small European duchy of Cagliostro to investigate some excellently-forged money and stumbles across a national conspiracy going back some hundreds of years. Lupin and his friends must rescue the beautiful Clarice from the hands of the evil Count Cagliostro and solve the mystery of a hidden treasure dating back to the 15th century.
