Frank Kelly Freas (August 27, 1922 – January 2, 2005) was an American artist known for his work in science fiction and fantasy, with a career spanning more than 50 years.

[6] The fantasy magazine Weird Tales published the first cover art by Freas on its November 1950 issue: "The Piper" illustrating "The Third Shadow" by H. Russell Wakefield.

[1] With his illustrating career underway, he continued to devise unique and imaginative concepts for other fantasy and science fiction magazines of that period.

In a field where airbrushing is common practice, paintings by Freas are notable for his use of bold brush strokes, and a study of his work reveals his experimentation with a wide variety of tools and techniques.

Over the next five decades, he created covers for hundreds of books and magazines (and much more interior artwork), notably Astounding Science Fiction, both before and after its title change to Analog, from 1953 to 2003.

Freas also painted insignia and posters for Skylab I;[4] pinup girls on bombers while in the United States Army Air Forces; comic book covers; the covers of the GURPS worldbooks Lensman and Planet Krishna; and more than 500 saints' portraits for the Franciscans executed simultaneously with his portraits of Alfred E. Neuman for Mad.

Freas was twice a Guest of Honor at Worldcon, at Chicon IV in 1982 and at Torcon 3 in 2003, although a fall suffered shortly before the latter convention precluded him from attending.
