Cypretherium coarctatum is an early entelodont from the Chadronian strata of the Cypress Hills Formation in Saskatchewan.{{Cite web|url=https://postagestampguide.com/stamps/18661/cypretherium-coarctatum-terminator-pig-dinosaur-2016-canada-postage-stamp-dinos-of-canada|title=Cypretherium Coarctatum (Terminator Pig) Dinosaur - Canada Postage Stamp {{!}} Dinos of Canada|website=postagestampguide.com|access-date=2019-05-22}}{{Cite web|url=https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=374520|title=Fossilworks: Cypretherium|website=fossilworks.org|access-date=17 December 2021}} First described by Cope in 1889, the holotype is a partial mandibular ramus with p2-m3.

The species is well represented by material from the Hunter Quarry, also in the Cypress Hills Fm. (Russell, 1980b).

The relationship of Cypretherium to other early entelodonts is not well understood at this point.
