thumb|upright=1.5|Schematic drawing of a virion of genus Mimivirus (cross section and side view) showing filaments ("hairs") and stargate (downside) Mimivirus is a genus of giant viruses, in the family Mimiviridae. It is believed that Amoeba serve as their natural hosts. It also refers to a group of phylogenetically related large viruses.

Megavirus is a viral genus, phylogenetically related to Acanthamoeba polyphaga mimivirus (APMV). In colloquial speech, Megavirus chilense is more commonly referred to as just "Megavirus". Until the discovery of pandoraviruses in 2013, it had the largest capsid diameter of all known viruses, as well as the largest and most complex genome among all known viruses.

Mimiviridae is a family of viruses. Amoeba and other protists serve as natural hosts. The family contains three subfamilies that contain ten genera. Viruses in this family belong to the nucleocytoplasmic large DNA virus clade (NCLDV), also referred to as giant viruses.

Mamavirus is a large and complex virus in the Group I family Mimiviridae. The virus is exceptionally large, and larger than many bacteria. Mamavirus and other mimiviridae belong to nucleocytoplasmic large DNA virus (NCLDVs) family. Mamavirus can be compared to the similar complex virus mimivirus; mamavirus was so named because it is similar to but larger than mimivirus.
