Apolinari wa Ierapoli (pia: Apolinari Klaudio au Apolinari Mtetezi wa Dini; alifariki karne ya 2) alikuwa askofu aliyeongoza kanisa la Ierapoli na kumuandikia kaisari Marcus Aurelius "Apologia", kitabu cha kutetea Wakristo dhidi ya dhuluma ya Dola la Roma (177). Aliandika pia vitabu vingine dhidi ya Upagani na uzushi. Hata hivyo zimetufikia sehemu chache, ile ndefu zaidi ikihusu tarehe ya Pasaka. Tangu kale anaheshimiwa na Wakatoliki na Waorthodoksi kama mtakatifu. Sikukuu yake huadhimishwa tarehe 8 Januari. Campbell, Thomas. "St. Apollinaris Claudius." The Catholic Encyclopedia Vol. 1.
