The Miraculous Blackhawk: Freedom's Champion, or just Blackhawk, is a 1952 American 15-chapter black-and-white movie serial adventure from Columbia Pictures, based on the comic book Blackhawk, published at the time by Quality Comics, but now owned by DC Comics. It was Columbia's forty-ninth serial. Home video release has since given the serial the tagline: "Fearless Champion of Freedom".

Blackhawk stars Kirk Alyn as Blackhawk and Carol Forman as the foreign spy that must be stopped from stealing the experimental super-fuel "Element-X"; Alyn and Forman were also the hero and villain of Columbia's earlier Superman. Blackhawk was produced by the famously cheap Sam Katzman and directed by the team of Spencer Gordon Bennet and Fred F. Sears. It is considered cheap and lackluster, made in the waning years of studio movie serial production.

A flying squadron of World War II veterans, The International Brotherhood, is a private flying investigative force led by Blackhawk. They uncover a gang of underworld henchmen, led by the notorious foreign spy Laska, who reports to The Leader, a mystery man. During the serial, Blackhawk and his flying squadron set about bringing these criminals to justice, following a series of cliff-hanger adventures.
