Dorothy Day (1897–1980) was a prominent American journalist and social activist who co-founded the Catholic Worker Movement in 1933 alongside Peter Maurin. This movement combined hospitality for the homeless with a commitment to social justice, operating houses of hospitality and publishing the "Catholic Worker" newspaper. Day's life was marked by her dedication to the poor and her advocacy for peace and nonviolence.

In 2000, the Vatican initiated the cause for her beatification, recognizing her as a Servant of God. Her cause remains under consideration, reflecting her enduring influence in the Church and society.

Pope Francis, during a homily in 2014, referred to Dorothy Day as "a woman of hope," highlighting her unwavering faith and resilience.
