Ludovico Avanzi (fl. 1556 - 1576) was an Italian printer and bookseller active in Venice during the third quarter of the sixteenth century. Nothing is known for his early years; his historical record consists of the appearances of his name on his works, and those executed in collaboration with other Venetian printers. His name appears on at least twenty nine printed editions from the 1550s to the early 1570s. He was most active between 1560 and 1566. It is probable that Avanzi died in the plague that wracked the city in the middle of the 1570s, and which appears to have hit that city's printing community disproportionately hard. No work of his has survived bearing his imprint after 1576.
