Adapisoriculidae is an extinct family of non-placental eutherian mammals which was present during the Paleogene and possibly the Late Cretaceous. They were once thought to be members of the order Erinaceomorpha,{{cite book

closely related to the hedgehog family (Erinaceidae), because of their similar dentition, or to be basal Euarchontans.{{cite journal |pages=417–22 |doi=10.1007/s00114-010-0651-5 |title=Euarchontan affinity of Paleocene Afro-European adapisoriculid mammals and their origin in the late Cretaceous Deccan Traps of India |year=2010 |last1=Smith |first1=Thierry |last2=Bast |first2=Eric |last3=Sigé |first3=Bernard |journal=Naturwissenschaften |volume=97 |issue=4 |pmid=20174778|bibcode=2010NW.....97..417S |s2cid=11529170 }} They were also thought to be marsupials at one point. Most recent studies show them to be non-placental eutherians, however.Carly L. Manz, Stephen G. B. Chester, Jonathan I. Bloch, Mary T. Silcox, Eric J. Sargis, New partial skeletons of Palaeocene Nyctitheriidae and evaluation of proposed euarchontan affinities, Published 14 January 2015.DOI: 10.1098/rsbl.2014.0911

They were small mammals of about 15 cm long, with a tail of equal length. They were probably nocturnal, eating insects and fruits.

Deccanolestes and Sahnitherium from the Late Cretaceous of India may be Cretaceous members of Adapisoriculidae.
