Girolamo della Volpaia (Florence, circa 1530 - 1614) was a clock-maker and constructor of scientific instruments, and continued the activities of his father Camillo della Volpaia and his uncles Benvenuto della Volpaia and Eufrosino della Volpaia. In 1554 he constructed an armillary sphere which is now conserved at the Science Museum of London. In 1560, he succeeded his father as curator of the great clock of the Palazzo Vecchio, and also asked to be given responsibility for the maintenance of the planetary clock built by his grandfather Lorenzo della Volpaia, which he had restored. In 1564 he planned a clock for Piazza S. Marco in Venice and in 1590 he made his last clock, now in the Museo di Storia della Scienza in Florence.
