This list of trilobites is a comprehensive listing of all genera that have ever been included in the Arthropod class Trilobita, excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (), or were not formally published (), as well as junior synonyms of more established names, and genera that are no longer considered trilobites.
