Zorro's Black Whip is a 1944 12-chapter film serial by Republic Pictures starring Linda Stirling. The film was made after the 1940 20th Century-Fox remake of The Mark of Zorro in order to capitalize on it. Republic was not able to use the character of Zorro himself, however, and despite the title, the hero(ine) is called The Black Whip throughout.

Man with the Steel Whip is a 1954 Republic Western serial film. It uses considerable stock footage from the previous Republic serials "Zorro's Black Whip", "The Painted Stallion" and "Daredevils of the West."
