Zorro's Black Whip is a 1944 Republic Pictures film serial starring Linda Stirling. The film was made after the popular 1940 20th Century-Fox remake of The Mark of Zorro and Republic was unable to use the character himself, but still wanted to capitalize on it. However, and despite the title, Zorro does not feature in this serial. The hero(ine) is actually called The Black Whip throughout.

The serial is set in pre-statehood Idaho, and involves a fight to prevent and ensure statehood by the villains and heroes respectively.

Parts of this serial were reused as stock footage to pad out later serials such as Don Daredevil Rides Again (1951) and Man with the Steel Whip (1954) - despite the fact that both of those serials had male leads.
