Vincenzo Scamozzi (2 September 1548 – 7 August 1616) was an Italian architect and a writer on architecture, active mainly in Vicenza and Republic of Venice area in the second half of the 16th century.

In 1599 to 1600, he visited the German Empire and France and left a sketchbook record of his impressions of French architecture, which first saw the light of day in 1959.

Scamozzi depended for sections of his treatment of Vitruvius on Daniele Barbaro's commentary, published in 1556 with illustrations by Palladio;[3] he also discussed issues of building practice.

His first book entitled Discorsi sopra l'antichita di Roma (Venice: Ziletti, 1583) had been quickly cobbled together with some illustrated commentary on the ruins of Rome, assembled in "the space of a few of days."

Eleven bays of this project were completed, and later were extended by Baldassare Longhena (Scamozzi's only pupil) to fill the whole south flank of the piazza.
