Luanne Platter is a character in the animated series King of the Hill. She is the niece of Peggy Hill and was a student at the local beauty academy. She moved in with the Hills after her mother, Leanne, was sent to jail for stabbing her dad with a fork. The Platter family trailer home flipped over following the stabbing incident. Hank Hill and friends (Dale Gribble, Bill Dauterive, and Boomhauer) tried to right the trailer home, using Hank's truck, but the trailer only brought bad memories back for Luanne.
Her longtime boyfriend, and one-time Mega Lo Mart employee, Buckley, was killed in a propane explosion at the Mega Lo Mart store during the season 2 cliffhanger episode.
She is the creator of the Manger Babies Christian puppet show.
She is named after the "Lu Ann Platter" dish served by the Luby's Texas cafeteria chain (parodied as "Luly's" in the series). The dish is a half portion of everything.
Luanne's voice is provided by Brittany Murphy.
