is a fictional character from the Nightmare on Elm Street series of films. The character was portrayed by Patricia Arquette in A Nightmare on Elm Street 3: Dream Warriors and by the singer-actress Tuesday Knight in A Nightmare on Elm Street 4: The Dream Master. According to Rachel Talalay, producer for Nightmare on Elm Street 4, Arquette was not approached by New Line to reprise the role.[18]

We first meet Kristen in part 3. She lives at home with her mother, Elaine Parker. She, like a handful of other children, (who are already at the Westin Hills mental facility) are all the last Elm Street children alive. Kristen tries to avoid sleeping by all costs by drinking caffeine, listening to loud music, swallowing coffee by the spoonful, and creating a papier-mâché version of the house from her nightmares, 1428 Elm Street. Finally, she falls asleep and is nearly killed by Freddy, who slits her wrists, making it look like a suicide attempt. She is then treated as a suicide threat and is the last to be admitted to Westin Hills where she meets the others who are tormented by the same man from all of their dreams. Kristen and the others then meet Nancy Thompson, the only person in the world that believes them and knows first hand what they are going through and exactly who is after them. With the help of Nancy, Kristen regains control of her telepathic ability to mentally pull people into her dream world. This was something she did with her father when she was a young girl and had not done since. Once she is able to invite people into her dreams again, Nancy assumes Kristen is the key to defeating Freddy. With the help of her friends (collectively known as the Dream Warriors) she was able to survive her first conflict with Freddy Krueger. Kristen's dream powers also include intense gymnastic/combat skills.

Part 4 begins sometime after being released from Westin Hills. Kristen, Kincaid and Joey return to school to lead a normal life. Kristen is getting along well with her new friends and her boyfriend, Rick Johnson. Soon she becomes paranoid that Freddy may be back. Her senses show true when he returns to kill both Joey and Kincaid in one night. Kristen freaks out when she notices that neither is in school one day. She knows he's back and begins her pattern behavior of avoiding sleep. Kristen's mother picks up on her behavior and slips her sleeping pills in her drink to force her to sleep. Eventually there's a showdown between her and Freddy. Kristen realizes she has no one left to call. All of the Elm Street children are dead and Freddy has come to collect the last little piggy. Kristen then calls Alice Johnson, who is able to control her dreams, into her dream. Once Kristen realizes what she has done, she apologizes to Alice and attempts to protect her by lunging at Krueger. Her attack backfires and Freddy throws Kristen into a lit furnace. Her last action was to unleash her powers to Alice, giving her the abilities Kristen had to battle Freddy. But this turns out not to be a good thing, partly because all it does is spread Freddy like a virus, and partly because Alice has her own way to handle Freddy. She is referred to by Freddy as "Elm Street's last brat" because she was the last survivor of the original Elm Street children whose parents got together and killed Krueger. Freddy was unable to access "fresh meat" without Kristen's help. Once she pulled Alice into her final dream, she opened a portal to new victims that he could only access when Alice was asleep. Kristen's actual death appeared as if she fell asleep with a lit cigarette and her bed caught on fire. She was the last remaining Elm Street
