Absolution is a theological term for the forgiveness imparted by ordained Christian priests and experienced by Christian penitents. It is a universal feature of the historic churches of Christendom, although the theology and the practice of absolution vary between Christian denominations.

Some Christian traditions see absolution as a sacrament — the Sacrament of Penance. This concept is found in the Catholic Church, Eastern Orthodox Church, Oriental Orthodox Churches, Assyrian Church of the East and the Lutheran Church. In other traditions, including the Anglican Communion and Methodism, absolution is seen as part of the sacramental life of the church, although both traditions are theologically predicated upon the Book of Common Prayer, which counts absolution amongst the five rites described as "Commonly called Sacraments, but not to be counted for Sacraments of the Gospel". Confession and Absolution is practiced in the Irvingian Churches, though it is not a sacrament.

The concept of private absolution within the life of the Church is largely rejected by the Reformed tradition that includes the Continental Reformed, Presbyterian and Congregationalist denominations.
