Party Girl is a 1930 American pre-Code crime film directed by Victor Halperin and starring Douglas Fairbanks Jr., Jeanette Loff, and Marie Prevost. It is also known by the alternative title of Dangerous Business, the title of the novel on which it is based. It follows a New York businessman who inadvertently becomes involved in the criminal activities of a covert escort agency.

The film holds the record for the longest transfer from banned status to original release in United Kingdom history, having been rejected for cinema release in 1930, and remaining unreleased there until 2003.
