Giovanni Boscoli (c.1524 - c.1592) was an Italian sculptor and architect, also known as Nanni da Montepulciano after his birthplace of Montepulciano. His father Tomaso was also an architect. He studied under Giorgio Vasari and moved to Parma in 1564 to work for duke Ottavio Farnese, for whom he designed the monumental fountain in front of the Palazzo del Giardino, from which he gained his nickname Giovanni della Fontana. He also designed the 'corridor' at the Palazzo della Pilotta in Parma. Outside the city he designed the villa Carona in Fornovo, the villa Paveri Fontana in Collecchio and the Borgo San Donnino fortifications.
