Peter Watts is a character in the TV series Millennium.

He left his position as Assistant Director of the FBI's Violent Crimes Task Force to join the Millennium Group which promised him, like as it did Frank Black, understanding in a chaotic world.

He would eventually become a senior member of the Group and patron to Frank, assisting him on numerous Group assigned cases.

He comes to realise the foulness of the Group and tries to expose them by giving Frank a folder of sensitive information. He was killed for his actions but managed to save Frank and Jordan's lives.
