John Celardo (December 27, 1918 – January 6, 2012) was an American comic strip and comic book artist, best known for illustrating the Tarzan comic strip.
Born on Staten Island, Celardo continued to live there most of his life. After a childhood in Mariners Harbor, he graduated from Port Richmond High School. He began his art career in the late 1930s drawing animals for the National Youth Administration at the Staten Island Zoo at West Brighton, where he was once photographed in the alligator pit by the Staten Island Advance.
