Our Lady of Peace, also otherwise known as the Queen of Peace, is a title of the Blessed Virgin Mary in the Roman Catholic Church. She is represented in art holding a dove and an olive branch, the two symbols of peace. The official date in which she is celebrated is on January 24 in the United States, and July 9 everywhere else.

Our Lady of Peace is the patroness of the Congregation of the Sacred Hearts of Jesus and Mary religious order, founded by Peter Coudrin in Paris during the French Revolution. When the Congregation of the Sacred Hearts of Jesus and Mary founded the Hawaii Catholic Church, they consecrated the Hawaiian Islands under the protection of Our Lady of Peace. They erected the first Roman Catholic Church in Hawaii to her. Today, the Cathedral of Our Lady of Peace in Honolulu is the oldest Roman Catholic cathedral in continuous use in the United States.
