{{further|DNA virus}}

Viruses with a DNA [[genome]], except for the DNA [[Virus classification#Reverse transcribing viruses|reverse transcribing viruses]], are members of three of the four recognized [[Realm (virology)|viral realms]]: ''[[Duplodnaviria]]'', ''[[Monodnaviria]]'', and ''[[Varidnaviria]]''. But the ''[[incertae sedis]]'' order ''[[Ligamenvirales]]'', and many other ''incertae sedis'' families and genera, are also used to classify DNA viruses. The domains ''Duplodnaviria'' and ''Varidnaviria'' consist of double-stranded DNA viruses; other double-stranded DNA viruses are ''incertae sedis''. The domain ''Monodnaviria'' consists of single-stranded DNA viruses that generally encode a [[HUH-tag|HUH]] [[endonuclease]]; other single-stranded DNA viruses are ''incertae sedis''.<ref name="Virus Taxonomy 2019">{{cite web|url=https://ictv.global/taxonomy|title=Virus Taxonomy: 2019 Release|website=talk.ictvonline.org|publisher=International Committee on Taxonomy of Viruses|access-date=26 April 2020}}</ref>
* '''Group I''': viruses possess double-stranded DNA. Viruses that cause [[chickenpox]] and [[herpes]] are found here.
* '''Group II''': viruses possess single-stranded DNA.
