In the Roman Catholic Church, a papal allocution (from the Latin allocutio, a commander's battle speech to his troops) is a solemn, private form of address or speech employed by the Pope on certain occasions.
Historically, papal allocutions were delivered only in a secret consistory of cardinals; popes since Pope Pius IX have made increasing use of allocutions, and modern allocutions may be delivered in private to any group.

The Pope prepares the allocution in consultation with his secretary of state, the cardinals in the consistorial congregation, and subject matter experts; although the allocution is delivered privately, it is usually published afterwards, in order to establish the stance of the Holy See on the relevant topic.
