Tracy Turnblad is the main protagonist of the 1988 film Hairspray and its stage musical adaption, and its 2007 musical film adaption. She is a teenager from Baltimore whose hair is a bouffant, much to her teacher's dismay because it keeps any student behind her from seeing the blackboard. Tracy is racially colorblind, causing her to support the integration of her favorite TV program The Corny Collins Show and has a love rivalry with the producer's bratty daughter Amber over Link. She also favors a monthly event on the show called "Negro Day", in which black people are on the show, while every day else in every month, everyone on the show is white. Eventually, she has the show integrated and encourages everyone to dance. In the original film, the stage musical adaption, and the 2007 film adaption, she is played by Ricki Lake, Marissa Jaret Winokur and (then-newcomer) Nikki Blonsky, respectively, all three of whom sang "Mama I'm a Big Girl Now" in the credits for the 2007 film.
In the 2007 film, Tracy's middle name is revealed to be Edna, after her mother.
