Plutonides is a genus of Middle Cambrian trilobite in the family Paradoxididae with species Plutonides sedgwickii and possibly Plutonides? illingi. Several other species and subspecies were at times placed in Plutonides but have subsequently been moved to other genera.

In terms of the Scandinavian Middle Cambrian sequence the genus ranges from the Baltoparadoxides oelandicus Biosuperzone (B. pinus Biosubzone) at the type locality for P. sedwickii on Trwyncynddeiriog headland located 1.3 km (0.81 mi) south-southwest of St David’s Cathedral and 500 m (1,600 ft) east of Porth Clais Harbour - Pen-y-Cyfrwy Member, Newgale Formation,^[1] and possibly to middle part of the Mawddachites hicksii Biozone on the Penpleidiau (eastern) Headland of Caerfai Bay south of St David’s in southwest Wales, where P? illingi occurs [Locs.
