Boris Badenov (Борис Баденов) is the main antagonist of the 1959-1964 animated cartoons Rocky and His Friends and The Bullwinkle Show, collectively referred to as The Rocky and Bullwinkle Show for short. He was voiced by Paul Frees.

Badenov's name is a play on that of the 16th-century Russian Tsar Boris Godunov ("bad enough" vs. "good enough"). His accent and explosive temper are an homage to Hollywood actor Akim Tamiroff, especially Tamiroff's role in The Great McGinty, a 1940 movie directed by Preston Sturges.

Boris is a spy for the fictional nation of Pottsylvania, and takes orders from the nation's leader, Fearless Leader (and occasionally the rarely seen Mr. Big). Boris's missions range from trying to steal a secret rocket fuel formula to eliminating all television from the United States as part of Pottsylvania's various attempts to seize power.
