Leopold Philip Fürst Montecuccoli (1663 – January 6, 1698) was an Austrian Field Marshal.
Leopold Philip Montecuccoli was the son of the famous Imperial Field Marshal Raimondo Montecuccoli and Maria Margareta von Dietrichstein (1637–1676), daughter of Max von Dietrichstein, Oberhofmeister of Ferdinand III, Holy Roman Emperor.
As his father, Leopold Philip entered in the service of the Imperial Habsburg army. When his father died in 1680, he took over command as Colonel of his Cuirassier-Regiment and became later Field Marshal-Lieutenant. He also became captain of the Imperial Trabanten-Leibgarde, Geheimrat and Knight in the Order of the Golden Fleece. In 1689 his title was raised to Reichsfürst. In 1695 Montecuccoli purchased a plot of land in the area of Laxenburg in order to establish a summer residence close to the Habsburg-family's castles. This plot was developed further after his death and is nowadays known under the name Palais Kaunitz-Wittgenstein.
He married Countess Maria Antonia Colloredo. When he died in 1698 at the age of 35, Philip and Maria had no children, and his title became extinct.
