'''Macrobaenidae''' is an extinct family of turtles, known from the Early Cretaceous to Paleogene of Laurasia. Their relationships to other turtles and whether they form a monophlyletic group are controversial. They are typically interpreted as stem or crown group cryptodires, but some more recent analyses have found them to lie outside crown group Testudines. Macrobaenids can be distinguished from other testudinatans by the presence of a carotid fenestra, cruciform plastron with strap-like epiplastra, and a lack of extragulars.<ref>{{Cite journal|last1=Joyce|first1=Walter G.|last2=Anquetin|first2=Jérémy|last3=Cadena|first3=Edwin-Alberto|last4=Claude|first4=Julien|last5=Danilov|first5=Igor G.|last6=Evers|first6=Serjoscha W.|last7=Ferreira|first7=Gabriel S.|last8=Gentry|first8=Andrew D.|last9=Georgalis|first9=Georgios L.|last10=Lyson|first10=Tyler R.|last11=Pérez-García|first11=Adán|date=December 2021|title=A nomenclature for fossil and living turtles using phylogenetically defined clade names|journal=Swiss Journal of Palaeontology|language=en|volume=140|issue=1|page=5|doi=10.1186/s13358-020-00211-x|issn=1664-2376|doi-access=free|bibcode=2021SwJP..140....5J |hdl=11336/155192|hdl-access=free}}</ref>
