The Extraordinary Jubilee of Mercy was a Catholic period of prayer held from 8 December 2015, the Solemnity of the Immaculate Conception, to 20 November 2016, the Feast of Christ the King. Like previous jubilees, it was seen by the Church as a period for remission of sins and universal pardon focusing particularly on God's forgiveness and mercy. It was an extraordinary Jubilee because it had not been predetermined long before; ordinary jubilees are usually celebrated every 25 years.

A jubilee is a special year of remission of sins, debts and universal pardon. In Leviticus, a jubilee year is mentioned to occur every 50th year; during which slaves and prisoners would be freed, debts would be forgiven and the mercies of God would be particularly manifest.
