G-Men vs. The Black Dragon (1943) is a Republic Pictures movie serial. It is noteworthy among adventure serials as containing an unusually high number of fistfights, all staged by director William Witney and a team of stuntmen.

This was Witney's last production before leaving to serve in World War II. He actually shipped out before filming was complete. It also sees the return of Witney's wife, Maxine Doyle, to acting for the first time since they met on the set of an earlier serial, S O S Coast Guard (1937).
