Percy Lee Crosby was an American author, illustrator and cartoonist best known for his comic strip Skippy. Adapted into movies, a novel and a radio show, Crosby's creation was commemorated on a 1997 U.S. Postal Service stamp. An inspiration for Charles Schulz's Peanuts, the strip is regarded by comics historian Maurice Horn as a "classic... which innovated a number of sophisticated and refined touches used later by Charles Schulz and Bill Watterson." Humorist Corey Ford, writing in Vanity Fair, praised the strip as "America's most important contribution to humor of the century".

Skippy is an American comic strip written and drawn by Percy Crosby that was published from 1923 to 1945. A highly popular, acclaimed and influential feature about rambunctious fifth-grader Skippy Skinner, his friends and his enemies, it was adapted into movies, a novel and a radio show. It was commemorated on a 1997 U.S. Postal Service stamp and was the basis for a wide range of merchandising—although perhaps the most well-known product bearing the Skippy name, Skippy peanut butter, used the name without Crosby's authorization, leading to a protracted trademark conflict.
