'''''Boreiohydrias''''' is an extinct genus of marine polymixiiform ray-finned fish, related to modern beardfish, that lived during the Turonian stage of the Late Cretaceous epoch. It is the only member of the family '''Boreiohydriidae'''.<ref name=":0" />

== Distribution == ''Boreiohydrias dayi'' is known from the shore of Lac des Bois in the Northwest Territories, Canada, in Turonian-aged sediments deposited in the aftermath of the Cenomanian-Turonian boundary event. This locality represents an open-water environment on the northern edge of the Western Interior Seaway, and is potentially correlated with the Cenomanian and Turonian-aged Slater River Formation.<ref name=":0">{{Cite journal |last1=Murray |first1=Alison M. |last2=Cumbaa |first2=Stephen L. |date=5 March 2013 |title=Early Turonian acanthomorphs from Lac des Bois, Northwest Territories, Canada |url=https://www.tandfonline.com/doi/full/10.1080/02724634.2013.722574 |journal=Journal of Vertebrate Paleontology |language=en |volume=33 |issue=2 |pages=293–300 |doi=10.1080/02724634.2013.722574 |issn=0272-4634 |access-date=25 June 2025 |via=Taylor and Francis Online|url-access=subscription }}</ref><ref>{{Cite journal |last=Cumbaa |first=Stephen L. |last2=Day |first2=Richard |last3=Gingras |first3=Murray |last4=Haggart |first4=James W. |last5=Holmes |first5=Robert B. |last6=Murray |first6=Alison M. |last7=Schröder-Adams |first7=Claudia |date=2018-11-01 |title=Lac des Bois, a locality in the northern Western Interior Seaway (Canada) with Tethyan faunal connections during the Cenomanian/Turonian Thermal Maximum |url=https://www.sciencedirect.com/science/article/pii/S0195667118301265 |journal=Cretaceous Research |volume=91 |pages=412–428 |doi=10.1016/j.cretres.2018.07.012 |issn=0195-6671|url-access=subscription }}</ref>
