Carroll Borland (February 25, 1914 – February 3, 1994), better known by the stage-spelling Carol Borland, was an American professor, writer, and actress.
 She is best known for having portrayed Luna, the daughter of Bela Lugosi's character, Count Mora, in "Mark of the Vampire", and for creating the iconic look of the female vampire with her waist-length dark hair and Adrian-designed shroud in this film.
 The visual designs of both the character of Lily Munster in the television series The Munsters and the female vampire in "Plan 9 from Outer Space" were based on her striking appearance.
 She was accused of wearing the "wiggiest wig in Hollywood," but claimed that the waist-length hair was her own.
 Her character does not speak through much of the film, but walks in a trance-like state until the end, when it is revealed that she and Lugosi are both actors who pretended to be vampires in order to catch a murderer.
 She was born in San Francisco, California.
 She was a drama student at UC Berkeley at the time she took the role.
 She had previously appeared in a stage production of "Dracula" with Lugosi, in a minor role as one of his victims.
