John Carl Schoenherr (July 5, 1935 – April 8, 2010) was an American illustrator. He won the 1988 Caldecott Medal for U.S. children's book illustration, recognizing Owl Moon by Jane Yolen, a father-and-daughter story where only Schoenherr's drawings reveal the child's gender. He was posthumously inducted by the Science Fiction and Fantasy Hall of Fame in 2015.
