Sandy, played by Megan Gray, is a character in the television series Buffy the Vampire Slayer.
Sandy first appears as a human in the Season Three episode "Doppelgangland" where she is bitten by the vampire version of Willow Rosenberg. While her fate in this episode is uncertain, in the Season Five episode "Family" a vampire by the same name and portrayed by the same actress shares a drink with Riley Finn at Willy's Bar, so it is assumed to be the same character. She later reappears in the Season Five episode "Shadow" where Riley allows her to drink some of his blood, only to stake her shortly thereafter.
