'''Planum Boreum''' ([[Latin]]: "dataran utara") adalah dataran yang terletak di kutub utara planet [[Mars]]. Dataran ini tebentang ke utara dari 80°N dan berpusat di {{Coord|88.0|15.0|globe:Mars}}. Dataran ini dikelilingi oleh dataran rendah yang disebut [[Vastitas Borealis]].<!--<ref>[http://planetarynames.wr.usgs.gov/jsp/FeatureNameDetail.jsp?feature=64923] and [http://planetarynames.wr.usgs.gov/jsp/FeatureNameDetail.jsp?feature=66502] give Vastitas Borealis starting at 54.7°N and Planum Boreum at 78.5°N. The radius of Mars is approximately 3400 km, so <math>d=\frac{78.5 - 54.7}{360}\times 2 \pi\ \times 3400\mbox{ km} = 1412\mbox{ km} </math></ref> -->
Di Planum Boreum terdapat [[lapisan es]] permanen yang terdiri dari es air (dan es karbon dioksida setebal 1 m selama musim dingin).<ref name="darling_marspoles">{{cite web|last=Darling|first=David|title=Mars, polar caps|work=Encyclopedia of Astrobiology, Astronomy, and Spaceflight|url=http://www.daviddarling.info/encyclopedia/M/Marspoles.html|accessdate=2007-02-26}}</ref> Volume lapisan tersebut tercatat sebesar 1,2 juta kilometer kubik dan meliputi wilayah seluas 1,5 kali [[Texas]]. Jari-jarinya diperkirakan sebesar 600 km. Kedalaman maksimal lapisan ini 3 km.<ref>{{cite web|url=http://ltpwww.gsfc.nasa.gov/tharsis/agu_f98.html|title=Laser provides first 3-D View of Mars' North Pole|accessdate=2006-11-01 |archiveurl = http://web.archive.org/web/20061017122112/http://ltpwww.gsfc.nasa.gov/tharsis/agu_f98.html <!-- Bot retrieved archive --> |archivedate = 2006-10-17}}</ref>
