The Second Epistle to the Corinthians is a Pauline epistle of the New Testament of the Christian Bible. The epistle is attributed to Paul the Apostle and a co-author named Timothy, and is addressed to the church in Corinth and Christians in the surrounding province of Achaea, in modern-day Greece. According to Jerome, Titus was the amanuensis of this epistle.

The Pauline epistles, also known as Epistles of Paul or Letters of Paul, are the thirteen books of the New Testament attributed to Paul the Apostle, although the authorship of some is in dispute. Among these epistles are some of the earliest extant Christian documents. They provide an insight into the beliefs and controversies of early Christianity. As part of the canon of the New Testament, they are foundational texts for both Christian theology and ethics.
