Antonio Mongitore (4 May 1663 – 6 June 1743) was a Sicilian presbyter, historian and writer, known for his works about the history of Sicily.

His education was, however, interrupted by the necessities of his family, and his aspirations to the priesthood frustrated by a regulation of the then Archbishop Jaime de Palafox y Cardona, who in an attempt to reduce the number of indigent priests, made a benefice a condition for ordination.

During this period of his life which corresponded to the Messina revolt and the attempt by Louis XIV to use this occasion to weaken an already tottering Spanish Empire, Mongitore began his life-long study of the history and privileges of the ancient Kingdom of Sicily.

His first book (1695) is a life of St. Francis de Sales and his last (1742) an account of the religious fervours of Palermo and Sicily in honour of the Immaculate Conception.

In this pages Mongitore collected all that had been written by his predecessors, about the Palermitan churches and monastic foundations and added his own comments based on his immense erudition and formidable powers of observation.
