Alfred III, Prince of Windisch-Grätz (German: Alfred August Karl Maria Wolfgang Erwin Fürst zu Windisch-Grätz; 31 October 1851, Prague – 23 November 1927, Tachov) was a Bohemian and Austrian nobleman, an Austro-Hungarian statesman who served as 11th Minister-President of Austria between 1893 and 1895, replacing Eduard Taaffe, 11th Viscount Taaffe, who previously held this position for 14 straight years.

Born into an old House of Windisch-Grätz, one of the most prominent Austrian noble families, he was the only child of Alfred II, Prince of Windisch-Grätz (1819-1876), Lieutenant field marshal in the Imperial Austrian Army, and his wife, Princess Hedwig of Lobkowicz (1829-1852), the eldest daughter of Prince August Longin Josef of Lobkowicz (1797-1848), Governor of Lombardy, and his wife, Princess Bertha of Schwarzenberg (1807-1883).

[1] His family owned large estates in the Western Bohemia, German-populated area near the border with Germany.

Alfred and his family resided in Tachov palace, Plzeň Region, which stayed in their possession until the beginning of WWII in 1939.

His grandfather, Alfred I, Prince of Windisch-Grätz had begun to transform an old Tachov castle into a town palace, but his plans remained partly unfulfilled.
