Gaius of Corinth was a first-century follower of Paul the Apostle. According to the New Testament, he lived in Corinth and was personally baptized by Paul, which served as a mark of distinction. He acted as a host to the apostle during Paul's stay in Corinth, which is noted to have occurred around 57 or 58 AD. Recognized as a saint, he remains a figure of historical and religious interest within early Christian traditions.
