Paladin is a genus of trilobite which lived 354–259 Ma, during the Late Paleozoic era; more specifically, during the Carboniferous and Permian periods.

It was widespread: fossils have been discovered in what are now East Asia, Europe and North America.

Approximately fifty species have been assigned to the genus;[5] the following are accepted:[2] This Trilobite-related article is a stub.
