Holmia is a genus of a well known group of extinct arthropods, the trilobites, that lived during the Lower Cambrian (Atdabanian) in what are now Scandinavia, Poland and Morocco.

Etymology

Holmia is the Latin name for Stockholm, in the neighborhood of which early finds of this trilobite were collected. H. kjerulfi was named in honor of the Norwegian geologist and paleontologist Theodor Kjerulf.
