Laura Ingalls Wilder Award, award presented to an author or illustrator of children's books published in the United States who has made a substantial and enduring contribution to the field of children's literature. The award was established in 1954 to honor Laura Ingalls Wilder, the author of the Little House series of books and the recipient of the first award. The Association for Library Service to Children, a division of the American Library Association, administers the award. The association originally presented the award every five years, then every three years between 1980 and 2001, when it switched to every two years. The winner receives a medal originally designed by Garth Williams, who illustrated the Little House books.
