John Brian Francis "Jack" Gaughan, pronounced like 'gone', was an American science fiction artist and illustrator and multiple winner of the Hugo Award in the category of Best Professional Artist.
Gaughan illustrated the covers and hand-lettered title pages for the unauthorized first paperback edition of J. R. R. Tolkien's The Lord of the Rings, which Ace released in 1965. A illustration Gaughan did of Samuel R. Delany was also used at the cover art for Delany's 1988 autobiography The Motion of Light in Water.
Beside his professional work, he was a frequent contributor to SF fan magazines. In his heyday he was often nominated for Hugo Awards for best professional artist and best fan artist. In 1967, he won both awards in the same year.
