Francesco Antonio Vallotti was an Italian composer, music theorist, and organist. He was born in Vercelli. He studied with G. A. Bissone at the church of St. Eusebius, and joined the Franciscan order in 1716. He was ordained as a priest in 1720. In 1722 he became an organist at St. Antonio in Padua, and would eventually become maestro there in 1730, succeeding maestro Calegari, and would hold that position for the next fifty years. Here he would meet and work with another theorist and composer named Giuseppe Tartini. Vallotti died in Padua on 10 January 1780.
