'''''Klosneuvirus''''' ('''KNV''', also '''KloV''') is a type of giant virus found by the analysis of low-complexity metagenomes from a wastewater treatment plant in Klosterneuburg, Austria. It has a 1.57-Mb genome coding unusually high number of genes typically found in cellular organisms, including aminoacyl transfer RNA synthetases with specificities for 19 different amino acids, over 10 translation factors and several tRNA-modifying enzymes.<ref>{{Cite journal|last1=Schulz|first1=Frederik|last2=Yutin|first2=Natalya|last3=Ivanova|first3=Natalia N.|last4=Ortega|first4=Davi R.|last5=Lee|first5=Tae Kwon|last6=Vierheilig|first6=Julia|last7=Daims|first7=Holger|last8=Horn|first8=Matthias|last9=Wagner|first9=Michael|date=2017-04-07|title=Giant viruses with an expanded complement of translation system components|journal=Science|language=en|volume=356|issue=6333|pages=82–85|doi=10.1126/science.aal4657|pmid=28386012|issn=0036-8075|bibcode=2017Sci...356...82S|doi-access=free}}</ref> ''Klosneuvirus'', ''Indivirus'', ''Catovirus'' and ''Hokovirus'', are part of a group of giant viruses denoted as Klosneuviruses or ''Klosneuvirinae'', a proposed subfamily of the ''Mimiviridae''.

Phylogenetic tree topology of ''Mimiviridae'' is still under discussion. As Klosneuviruses are related to ''Mimivirus'', it was proposed to put them all together into a subfamily ''Megavirinae''.<ref name="Deeg2018" /> Other authors (CNS 2018) like to put Klosneuviruses just together with ''Cafeteria roenbergensis virus'' (CroV) and ''Bodo saltans virus'' (BsV) into a tentative subfamily called ''Aquavirinae''.<ref>Centre national de la recherche scientifique (CNS): [http://www.igs.cnrs-mrs.fr/wp-content/uploads/2018/05/TableVirus18_04_18.pdf List of the main “giant” viruses known as of today] {{Webarchive|url=https://web.archive.org/web/20190111233355/http://www.igs.cnrs-mrs.fr/wp-content/uploads/2018/05/TableVirus18_04_18.pdf |date=2019-01-11 }}, Université Aix Marseille, 18.
