Harold Robert Millar (1869 – 1942) was a prominent and prolific Scottish graphic artist and illustrator of the late nineteenth and early twentieth centuries. He is best known for his illustrations of children's books and fantasy literature. A native of Dumfriesshire, Millar first pursued civil engineering before deciding upon an artistic career. He then studied at the WolverhamptonArtSchool and the Birmingham School of Art, and established his career as a magazine illustrator with Punch, Good Words, and other periodicals of the day.
Millar illustrated fables for the Strand Magazine, and anthologies of tales, The Golden Fairy Book, The Silver Fairy Book, The Diamond Fairy Book, and The Ruby Fairy Book. He illustrated books by a wide range of British authors of his time, including Sir Arthur Quiller-Couch, Robert Louis Stevenson, and Rudyard Kipling. He had an extensive working relationship with E. Nesbit, and has been called "the most sympathetic and perhaps the most talented of her illustrators."
