Emily Winfield Martin is an American artist and author-illustrator of children's books. She has said that, “when she was small, she spent every moment drawing, reading, dressing rabbits in fancy clothes, and having many peculiar daydreams.” When she grew up, she started “to illustrate those daydreams”, which has grown into a cottage industry called The Black Apple, where she sells all of her art.

After graduating from art school in 2005, Emily began selling her visual art through the online store Etsy, where she achieved major acclaim from The New York Times, CNN, and The Martha Stewart Show, as one of Etsy's original and most enduring success stories. Eventually, Emily turned these successes into a career in professional book publication.
