Stachys the Apostle was a Christian minister who served as the second bishop of Byzantium between 38 and 54 AD. According to church tradition, he was appointed to this position by the Apostle Andrew, who established the see in the region. While his historical details are limited, he is identified in the New Testament in the Epistle to the Romans as a person beloved by Paul the Apostle. He is traditionally linked to several other apostles mentioned in the same Pauline greeting.
