Histiogamphelus is a genus of fish of the family syngnathidae endemic to the southern coast of Australia and Tasmania. They have a characteristic "crest" on the snout, distinguishing them from pipefish which are of the same family. Their brown-tan coloration mimics the Posidonia sea grass which covers their habitat. Like all syngnathids, the male broods the eggs in a brood pouch (in this genus located under the tail).
