Dan "Terrible" Turpin is a fictional character from DC Comics. He is a police inspector in Metropolis.

He was created by Jack Kirby and first appeared in New Gods #5 in 1971, when he was encountered by Orion. He was a tough, no-nonsense cop nicknamed "Terrible" Turpin.

In current Superman titles, Inspector Turpin is a member of the Metropolis Special Crimes Unit. He was extremely loyal to Inspector Sawyer, before her transfer to Gotham City, and was romantically interested in her before learning she was a lesbian.

Possibly inspired by his attitude, and the fact he always wears a derby hat, later writers have revealed him to be the adult version of Kirby's Golden Age "kid-gang" character Brooklyn, of the Boy Commandos .

In Superman: The Animated Series, Turpin was modelled on Kirby, and voiced by Joseph Bologna. In the series, he was killed by Darkseid's forces.
