Scalacurvichthys (meaning "curved scale fish") is an extinct genus of pycnodontine pycnodontiform fish from the Amminadav Formation or Bet-Meir Formation in the West Bank; Palestine.

This is in reference to the raised, anterior-facing first dorsal ridge scale protruding above the skull roof.

The specific name, naishi, is dedicated to Dr. Darren Naish, who is a prominent palaeontologist and the founder of the vertebrate palaeozoology blog Tetrapod Zoology, and its accompanying convention TetZooCon.

It consists of an almost completely and fully articulated specimen, however, it is lacking some cranial and postcranial details due to taphonomic processes.
