Stylonurus is a genus of prehistoric eurypterid of the family Stylonuridae. The genus contains three species: Stylonurus powriensis from the Devonian of Scotland, Stylonurus shaffneri from the Devonian of Pennsylvania and Stylonurus perspicillum from the Devonian of Germany.[1]

The assignment of S. perspicillum and S. schaffneri to the genus is doubtful. A previously assigned species, S. ensiformis, is today regarded as synonymous with S. powriensis.[1]
