Urban Legends: Bloody Mary (also known as Urban Legends 3: Bloody Mary or simply Urban Legend 3) is a 2005 American direct-to-video supernatural slasher film directed by Mary Lambert, and starring Kate Mara, Robert Vito, Tina Lifford, Ed Marinaro and Lillith Fields.

It is the third and final installment in the Urban Legend film series, although it is almost entirely unrelated to both of the films that came before it, using supernatural elements instead of a whodunit formula. The film follows three high school students who inadvertently summon the ghost of a dead high-school girl, who starts coming after her old classmates.
