Pinheirodontidae is a poorly known family of fossil mammals which belong to the informal suborder "Plagiaulacida" within the order Multituberculata. Remains are known from the Late Jurassic to Early Cretaceous of Europe (predominantly Portugal and Spain), but are so far restricted to isolated teeth, as well as a single lower jaw.{{Cite journal |last=Carvalho |first=Victor F. |last2=Camilo |first2=Bruno |last3=Araújo |first3=Ricardo |last4=Castro |first4=Lígia |last5=Kullberg |first5=José C. |last6=Desmet |first6=Hilde G.

Their closest relatives are believed to be Paulchoffatiidae. Cladogram after Carvalho et al. 2025{{clade|{{clade
