Girolamo Scotto (Hieronymus Scotus; also Gerolamo) (c.1505 – 3 September 1572) was an Italian printer, composer, businessman and bookseller of the Renaissance, active mainly in Venice. He was the most influential member of the firm of Venetian printers, the House of Scotto, which existed from the late 15th century until 1615. At its peak in the 1560s, the Scotto firm under Girolamo was one of the preeminent publishing firms of Europe, producing volumes on law, scholasticism, philosophy, medicine, theology, and ancient literature in addition to music. Only the firm of Gardano produced more books of music in the 16th century than the House of Scotto under Girolamo; over half of Scotto's publications, 409 out of approximately 800 in total, were books of music.
