The Dialogue of Divine Providence is a spiritual treatise written by Catherine of Siena, Italian mystic and saint. The book presents a dialogue between a soul who "rises up" to God and God himself. Contemporaries of Catherine are united in asserting that much of the book was dictated while Catherine was in ecstasy. The Dialogue is highly systematic and explanatory in its presentation of her mystical ideas which are based in her ecstatic mystical experience.

Catherine of Siena (1347-1380) was an Italian member of the Third Order of Saint Dominic in the Roman Catholic Church. She was a mystic, activist, and author who had a great influence on Italian literature and on the Catholic Church. Catherine's theology can be described as mystical, and was employed toward practical ends for her own spiritual life or those of others. Her major treatise is The Dialogue of Divine Providence.
