Fritzolenellus is an extinct genus from a well-known class of fossil marine arthropods, the trilobites, with three known species. It lived during the early part of the Botomian stage, which lasted from approximately 524 to 518.5 million years ago. This faunal stage was part of the Cambrian Period. Fritzolenellus occurred in parts of the paleocontinent Laurentia in what are now Northwestern Canada, Northwestern Scotland, and North-Greenland.

Fritzolenellus is the genus closest to the common ancestor of Mummaspis, Laudonia, the Biceratopsinae and the Bristoliinae. This clade is the sister group Wanneria walcottana and of the Holmiidae.

The generic name is a combination of the distantly related genus Olenellus and a reference to W.H. Fritz, a paleontologist who worked on olenelloid trilobites. The species names have the following derivation.
