Nuggan is a fictional character in Terry Pratchett's Discworld books. He is the god of Borogravia, has charge of paperclips and unnecessary paperwork, and sports a fussy little moustache.

He first appeared in The Last Hero by Terry Pratchett, heavily illustrated by Paul Kidby. At that time he prohibited the eating of chocolate, ginger, mushrooms, and garlic by his followers.

His existence is the basis for Terry Pratchett's latest novel Monstrous Regiment. Among his ever-growing list of Abominations are chocolate, cats, the color Blue, Dwarfs, Oysters, babies, cheese, the smell of beets, and ears.

He is thought to be either insane or dead.
