Troa (kwa Kigiriki: Τρωάδα, Troáda; awali: Τρῳάς, Trōiás au Τρωϊάς, Trōïás; kwa Kituruki: Biga Yarımadası) ni jina la zamani la rasi ya Uturuki, kaskazini magharibi mwa rasi ya Anatolia. Mtume Paulo (akiwa na Sila) alifikia eneo hilo katika safari yake ya pili ya kimisionari, kutoka Galatia kwenda Makedonia. Inawezekana huko Luka alianza kuongozana naye pia . Ni huko Troa kwamba Paulo, wakati wa ibada ya Jumapili, alimfufua Eutiko kadiri ya Mdo 20:7-12. Baadaye Paulo alitaja Troa alipomuandikia Timotheo amletee joho aliloliacha huko. Mdo 16:8 na 2Kor 2:12 The changes from the story, being recounted as "they" to "we" in Acts 16 and Acts 20, imply that Paul was joined by Luke when he went through Troas. 20:7 And upon the first day of the week, when the disciples came together to break bread, Paul preached unto them, ready to depart on the morrow; and continued his speech until midnight. 8 And there were many lights in the upper chamber, where they were gathered together.
