Clara Claiborne Park (August 19, 1923 – July 3, 2010) was an American college English teacher and author who was best known for her writings about her experiences raising her autistic daughter, the artist Jessica Park. Her 1967 book, The Siege was credited as one of the first books to allay the blame that parents, especially mothers, were made to feel at having caused their child's autism through their cold detachment.
