Donato Bramante (1444 – 11 March 1514) was an Italian architect, who introduced the Early Renaissance style to Milan and the High Renaissance style to Rome, where his most famous design was St. Peter's Basilica.

Bramante was born in Monte Asdrualdo (now Fermignano), under name Donato di Pascuccio d'Antonio, near Urbino: here, in 1467 Luciano Laurana was adding to the Palazzo Ducale an arcaded courtyard and other features that seemed to have the true ring of a reborn antiquity to Federico da Montefeltro's ducal palace.

Bramante's architecture has eclipsed his painting skills: he knew the painters Melozzo da Forlì and Piero della Francesca well, who were interested in the rules of perspective and illusionistic features in Mantegna's painting. Around 1474, Bramante moved to Milan, a city with a deep Gothic architectural tradition, and built several churches in the new Antique style. The Duke, Ludovico Sforza, made him virtually his court architect, beginning in 1476, with commissions that culminated in the famous trompe-l'oeil choir of the church of Santa Maria presso San Satiro (1482–1486). Space was limited, and Bramante made a theatrical apse in bas-relief, combining the painterly arts of perspective with Roman details. There is an octagonal sacristy, surmounted by a dome.
