Dicrostonychini is a tribe of lemmings in the subfamily Arvicolinae. It contains only one extant genus, as well as one extinct genus.

A 2021 study found Dicrostonychini to also include the genera previously placed in the tribe Phenacomyini, and found this combined Dicrostonychini to be the sister group to the muskrats (tribe Ondatrini).{{Cite journal|last1=Abramson|first1=Natalia I.|last2=Bodrov|first2=Semyon Yu|last3=Bondareva|first3=Olga V.|last4=Genelt-Yanovskiy|first4=Evgeny A.|last5=Petrova|first5=Tatyana V.|date=2021-11-19|title=A mitochondrial genome phylogeny of voles and lemmings (Rodentia: Arvicolinae): Evolutionary and taxonomic implications|journal=PLOS ONE|language=en|volume=16|issue=11|pages=e0248198|doi=10.1371/journal.pone.0248198|issn=1932-6203|pmc=8604340|pmid=34797834|bibcode=2021PLoSO..1648198A |doi-access=free }}
