'''''Mezenia''''' is a genus of macroalgae described by Boris Sokolov in 1976. ''Mezenia'' lived in Eurasia during the Ediacaran between 560 and 551 Ma.

== Description == ''Mezenia kossovoyi'', the only described species, was described by Boris Sokolov in 1976.<ref name="Sokolov 1976" />

The original ''Mezenia'' specimen was described as sausage shaped, and 5–6&nbsp;mm wide.<ref name="Sokolov 1976">{{Cite journal|last=Sokolov|first=B.

== Distribution == ''Mezenia kossovoyi'' specimens are found in the Khatyspyt Formation, the Perevalok Formation, and the Lyamatsa Formation, all of which are in Russia. The Khatyspyt Formation is in northern Siberia, the Perevalok Formation is on the western slope of the Central Ural Mountains, and the Lyamatsa Formation is in the White Sea area.<ref name="Marusin 2011" /><ref>{{Cite journal|last1=Grazhdankin|first1=Dmitriy V.|last2=Balthasar|first2=Uwe|last3=Nagovitsin|first3=Konstantin E.|last4=Kochnev|first4=Boris B.|date=2008|title=Carbonate-hosted Avalon-type fossils in arctic Siberia|journal=Geology|volume=36|issue=10|pages=803|doi=10.1130/g24946a.1|bibcode=2008Geo....36..803G}}</ref><ref name="Bykova 2017">{{Cite journal|last1=Bykova|first1=N.|last2=Gill|first2=B.

== Taphonomy == ''Mezenia kossovoyi'' has been preserved as carbonaceous compressions in mudstone.<ref name="Bykova 2017" /> Specimens from the Lyamatsa formation had longitudinal and transverse wrinkles created during burial on their otherwise smooth surfaces.<ref>{{Cite journal|last1=Grazhdankin|first1=D.
