Olethreutes is a large genus of tortrix moths (family Tortricidae). It is the type genus of its tribe (Olethreutini) and subfamily (Olethreutinae).

Celyphoides, Loxoterma and Paracelypha are sometimes listed as junior synonyms of Olethreutes. But the type species of the first is Tortrix flavipalpana (now Celypha flavipalpana), that of the second is T. latifasciana (now C. aurofasciana), and that of the third is Phalaena rivulana (now Syricoris rivulana). This makes Celyphoides and Loxoterma junior subjective synonyms of Celypha and Paracelypha a junior subjective synonym of Syricoris, at least according to the present delimitation of these genera.
