Paranyctoides is an extinct genus of early eutherian mammal from the Late Cretaceous of North America and possibly Asia.

Material from the Maastrichtian Hell Creek and Lance Formations, as well as P. megakeros, have since been identified as Alostera saskatchewanensis, limiting Paranyctoides to the Santonian to Campanian in North America.

[1][2] Species of Paranyctoides have also been identified from Uzbekistan, first being named P. aralensis by Lev Nesov in 1993 for material from the Turonian Bissekty Formation.

Additional Asian specimens were found and referred to Paranyctoides expanding its range to the younger Aitym Formation, before Averianov and Archibald considered that all the Uzbek specimens belonged to the same species, which they identified as P. quadrans, being an older name Nesov had coined in 1982 for a species of Sailestes.

[2] The referral of Asian species and material to Paranyctoides was not supported by Montellano-Ballesteros and colleagues, though it was found within the genus in a phylogenetic analysis by Averinanov and Archibald.
