Perils of Nyoka is a 1942 Republic serial directed by William Witney. It starred Kay Aldridge as Nyoka the Jungle Girl, a character who first appeared in the Edgar Rice Burroughs-inspired serial Jungle Girl.

Plot
Nyoka, with help from Larry Grayson, attempts to discover the Golden Tablets of Hippocrates. The tablets contain the medical knowledge of the Ancients — not to mention being buried along with gold and other treasure. Also hunting for the tablets are Queen Vultura (“Ruler of the Arabs”) and Cassib.

Cast
Kay Aldridge as Nyoka Gordon. Aldridge replaced Frances Gifford as Nyoka. The success and popularity she gained from her role in this serial made Kay Aldridge the star of several of the better Republic serials for years after its release. In his autobiography, director William Witney stated that the studio decided to use a different actress just to further ensure that there would be no actionable copyright infringement. Ray Stedman, however, writes that Gifford was not cast in this serial because she had been on loan from another studio for Jungle Girl and was not available for the filming of this serial. Cline partially backs this point of view, saying that Gifford was unavailable to reprise her role because she had moved on to feature films.
