Franz Georg von Schönborn (15 June 1682 – 18 January 1756) was the Archbishop-Elector of Trier from 1729 until 1756, and the Prince-Bishop of Worms and Prince-Provost of Ellwangen from 1732 until 1756.
Franz Georg was born in Mainz, the ninth son of the Count of Schönborn and the nephew of Lothar Franz von Schönborn, the Archbishop-Elector of Mainz. Franz Georg's brothers were Johann Philipp Franz, Friedrich Karl and Hugo Damian, all three important churchmen. Beginning in 1702 he studied law, philosophy, theology, geography, history, and language at Salzburg, Siena, and Leiden. After completing his studies he travelled to the Vatican, Spain, and England. Through the influence of his uncle, Franz Georg gained valuable contacts in the court of the Holy Roman Emperor in Vienna. After his uncle died in 1729 and Franz Ludwig, Archbishop-Elector of Trier, succeeded him after vacating his own see, Franz Georg was unanimously elected the new Archbishop of Trier and thus appointed Prince-Elector of Trier. Owing to the protection of the Papacy in 1732 he was also elected the Prince-Bishop of Worms and the Prince-Provost of Ellwangen Abbey.
