The mass in Birmingham on September 19 will come at the end of the pope's four-day visit to Britain which will also include a meeting with Queen Elizabeth II.
It will mark the beatification of Cardinal John Henry Newman, a Protestant who converted to Catholicism and died in 1890.
Benedict XVI will be only the second pope to visit Britain since King Henry VIII split with Rome in 1534, leading to the formation of the Anglican church.
Pope John Paul II visited Britain, where over four million of some 61 million inhabitants are Catholic, in 1982.
