Jack Skellington, also known as the "Pumpkin King", is the main protagonist of Tim Burton's The Nightmare Before Christmas and all Nightmare Before Christmas media.

Jack is an extremely tall skeleton who wears a black pin-striped suit, complete with a bat bow-tie and black dress shoes.

He has earned the title of Pumpkin King by being terrifying to humans (but never harming them), a clearly well-earned title as it appears he is even able to scare the monsters that occupy the town. He lives in Halloween Town, a world based solely on the holiday of Halloween. (Note: Halloween is on October 31 every year.)
