Boris Badenov (Борис Баденов) is a fictional character in the 1960s animated cartoons Rocky and His Friends and The Bullwinkle Show, collectively referred to as Rocky and Bullwinkle for short. He is 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.
