Heinrich Franz von Mansfeld, Prince of Fondi (Bornstedt, November 21, 1640, Vienna, June 18, 1715) was an Austrian diplomat, Field marshal and President of the Hofkriegsrat.
In 1703 Mansfeld, who was unpopular with most Army generals, was relieved of this post and replaced by Eugene of Savoy.
In 1690, he accompanied Princess Maria Anna of Pfalz-Neuburg as bride of King Charles II of Spain to her wedding in Valladolid.
From 1697, he had Johann Lukas von Hildebrandt build a pleasure palace with a garden, which still unfinished, the Schwarzenberg family acquired after his death.
In 1679, he married Countess Marie Louise of Aspremont-Lynden, widow of Charles IV, Duke of Lorraine.
