Trina Schart Hyman (April 8, 1939 – November 19, 2004) was an American illustrator of children's books. She illustrated over 150 books, including fairy tales and Arthurian legends. She won the 1985 Caldecott Medal for U.S. picture book illustration, recognizing Saint George and the Dragon, retold by Margaret Hodges.
Born in Philadelphia to Margaret Doris Bruck and Albert H. Schart, she grew up in a rural area of Pennsylvania and learned to read and draw at an early age. Her favorite story as a child was Little Red Riding Hood, and she spent an entire year of her childhood wearing a red cape.
She enrolled at the Philadelphia Museum College of Art (now part of the University of the Arts) in 1956, but moved to Boston, Massachusetts, in 1959 after marrying Harris Hyman, a mathematician and engineer. She graduated from School of the Museum of Fine Arts, Boston, in 1960.
The couple then moved to , for two years, where Trina studied at the Konstfackskolan (Swedish State Art School) and illustrated her first children's book, titled Toffe och den lilla bilen (Toffe and the Little Car).
In 1963, the couple's daughter, Katrin Tchana (née Hyman), was born, but in 1968, they divorced, and Trina and Katrin moved to Lyme, New Hampshire. Trina lived for some time with children's writer and editor Barbara Rogasky (with whom she collaborated on several projects). For about the last decade of her life, her romantic partner was teacher Jean K. Aull. She was the first art director of Cricket Magazine, from 1973 to 1979, and contributed illustrations regularly until her death.
