Amphinomida is an order of marine polychaetes. The order contains two families:
Amphinomidae Lamarck, 1818
Euphrosinidae Williams, 1852
The fossil record of this taxon (not abundant in annelids overall because this taxon lacks a mineralized skeleton) includes Palaeocampa anthrax Meek & Worthen, 1865 from the Late Carboniferous site of Montceau-les-Mines.
