Antilegomena, a direct transliteration of the Greek ἀντιλεγόμενα, refers to written texts whose authenticity or value is disputed.
Eusebius in his Church History written c. 325 used the term for those Christian scriptures that were "disputed" or literally those works which were "spoken against" in Early Christianity, before the closure of the New Testament canon.
