Shergoldana is an extinct genus of fossil bilaterian worm-like organisms known from the Middle Cambrian of Australia. It is described as having common features with Nemathelminthes, with a possible relation to an adult kinorhynch or to the larval stage of a palaeoscolecid worm. It has been described as the first occurrence of a free living cycloneuralian from the Cambrian period.
