George Baker (May 22, 1915 – May 7, 1975) was a cartoonist who became prominent during World War II as the creator of the popular comic strip The Sad Sack.

After six weeks of art training in a night school, he got a job as a commercial artist "but soon grew tired of drawing pots and pans for newspaper advertisements.

Instead, he was hired by Walt Disney in 1937, and assisted in the production of the studio's full-length animated features, including Pinocchio, Fantasia, Dumbo and Bambi.

Drawn in pantomime, the strip became the magazine's most popular feature, as measured by the fan mail from servicemen who identified with the luckless private.

In an official document, General George C. Marshall praised Sad Sack as a morale-booster for World War II troops.
