Satyrichthys is a genus of marine ray-finned fish belonging to the family Peristediidae, the armoured gurnards or armored searobins.

Satyrichthys was first described as a monotypic genus in 1873 by the German zoologist Johann Jakob Kaup with Peristethus rieffeli as its only species.

[3] The name of the genus Satyrichtys was not explained by Kaup but it combines satyr, meaning "god" or "demon", with ichthys, meaning "fish", the first part may be an allusion to the two fork-shaped projections at the end of the snout of S. rieffeli, resembling the horns depicted on demons.

The rear scutes in the lower lateral rows are not joined to the ventral midline.

[7] The smallest of these fishes is S. longiceps which has a maximum published standard length of 15.5 cm (6.1 in) while the largest is S. laticeps which has a maximum published standard length of 48.7 cm (19.2 in).
