Olenellus is an extinct genus of redlichiid trilobites, with species of average size (about 5 centimetres or 2.0 inches long). It lived during the Botomian and Toyonian stages of the Lower Cambrian (Olenellus-zone), 522 to 510 million years ago, in what is currently North America, part of the palaeocontinent Laurentia.
