Tina Williams, played by Wendy Kaplan, is a character in the film Halloween 5: The Revenge of Michael Myers.
Tina is the best friend of Rachel Carruthers and Samantha Thomas in Halloween 5. Her boyfriend is Michael Gonland. When Jamie Lloyd tells her about the vision she had of Michael Myers, Tina dismisses it and goes to a Halloween party at a farm with Samantha and her boyfriend Spitz.
While at the party she is bothered about Mike not arriving and unaware that he has been murdered by Michael. She then goes to the barn, while Jamie and her young friend Billy Hill arrive at the farm, worried about Tina. After finding Samantha and Spitz murdered in the barn and seeing Michael, Tina runs outside to seek help, only to find the police officers sent to protect her already dead.
Michael begins to chase Jamie, Billy and Tina in the car he stole from Mike, until they go into the woods and he crashes. However, he emerges from the wreckage and continues to pursue them. During the chase, Michael fatally stabs Tina.
