Wes Wrench and Grady Numbers, mostly known as Mr. Wrench and Mr. Numbers, are fictional characters of the FX television series Fargo, most prominently appearing as antagonists in the first season. The characters, portrayed respectively by Russell Harvard and Adam Goldberg, were often highlighted as one of the stand-outs of season one by critics.

Fargo is an American black comedy crime drama television series created and primarily written by Noah Hawley. It is based on the 1996 film of the same name, which was written and directed by the Coen brothers, and takes place in the American Midwest, primarily Minnesota, within the same continuity as the film. The Coens were impressed by Hawley's script and agreed to be named as executive producers. The series premiered on April 15, 2014, on FX, and follows an anthology format, with each season set in a different era and location, with a different story and mostly new characters and cast, although there is minor overlap. Each season is heavily influenced by various Coen brothers films, with each containing numerous references to them.
