Baboushka and the Three Kings is a children's picture book written by Ruth Robbins, illustrated by Nicolas Sidjakov, and published by Parnassus Press in 1960. Sidjakov won the annual Caldecott Medal as illustrator of the year's "most distinguished American picture book for children". Parnassus was a small press in Berkeley, California, established in 1957 by Herman Schein, the husband of writer-illustrator Ruth Robbins. Sidjakov illustrated one of its first books and during the next several years it published at least three picture books he created with Robbins as writer.
