Paul the Apostle (; c. 5 – c. 67), originally known as Saul of Tarsus (; ), was an apostle (though not one of the Twelve Apostles) who taught the gospel of Christ to the first-century world. He is generally considered one of the most important figures of the Apostolic Age. In the mid-30s to the mid-50s, he founded several churches in Asia Minor and Europe. Paul took advantage of his status as both a Jew and a Roman citizen to minister to both Jewish and Roman audiences.

Saint Paul and Apostle Paul usually refers to Paul the Apostle, the Christian religious leader.
