Matthias (; Koine Greek: Μαθθίας, Matthías [maθˈθi.as], from Hebrew מַתִּתְיָהוּ Mattiṯyāhū; Coptic: ⲙⲁⲑⲓⲁⲥ; died c. AD 80) was an apostle in Christianity. According to the Acts of the Apostles, he was chosen by God through the remaining apostles to replace Judas Iscariot following the latter's betrayal of Jesus and his subsequent death. His calling as an apostle is unique, in that he was, despite having known Jesus throughout the latter's earthly history, selected via the casting of lots following Jesus' ascension to heaven.
