The ''Flaviviridae'' are part of [[RNA virus supergroup II]], which includes certain plant viruses and bacterial viruses.<ref name="ICTVReport" />

The family has four genera:<ref name="ICTVProfile" /><ref name="ICTVReport" />
*Genus ''[[Flavivirus]],'' renamed ''Orthoflavivirus'' in 2023, (includes [[Dengue virus]], [[Japanese encephalitis virus]], [[Kyasanur Forest disease virus]], [[Powassan virus]], [[West Nile virus]], [[Yellow fever virus]], and [[Zika virus]])
*Genus ''[[Hepacivirus]]'' (includes [[hepatitis C virus]] and GB virus B)
*Genus ''[[Pegivirus]]'' (includes GB virus A, GB virus C, and GB virus D))
*Genus ''[[Pestivirus]]'' (includes [[bovine viral diarrhea virus|bovine viral diarrhea virus 1]]) and [[classical swine fever virus]], previously hog cholera virus)). Viruses in this genus infect nonhuman mammals.

;Unclassified

Other Orthoflaviviruses are known that have yet to be classified. These include Wenling shark virus.

[[Jingmenvirus]] is a group of unclassified viruses in the family which includes [[Alongshan virus]], Guaico Culex virus, Jingmen tick virus and Mogiana tick virus. These viruses have a segmented genome of four or five pieces. Two of these segments are derived from flaviviruses.{{citation needed|date=July 2024}}

A number of viruses may be related to the flaviviruses, but have features that are atypical of the flaviviruses. These include citrus Jingmen-like virus, soybean cyst nematode virus 5, Toxocara canis larva agent, Wuhan cricket virus, and possibly Gentian Kobu-sho-associated virus.{{citation needed|date=July 2024}}
