Shermy was an early character in the comic strip Peanuts, by Charles Schulz. Though he appeared in the first strip, he soon began to be eclipsed by newer characters who were more developed, such as Linus and Lucy. His disappearance from the strip was even faster and more complete than the other the early characters, Patty and Violet. Shermy's major physical characteristic was his short cropped hair.

Shermy had one line of dialogue in the 1965 animated TV special A Charlie Brown Christmas. Upon being cast as a shepherd in the gang's Christmas pageant, he laments, "Every Christmas it's the same: I always end up playing a shepherd."

Shermy pretty muched stopped appearing in the comic strip by 1970. He was once referred to by name in a 1977 strip in which Charlie Brown and Lucy are discussing players on their baseball team. Shermy usually was shown playing first base on Charlie Brown's baseball team, although this strip referred to him as their designated hitter.
