Prince Ludwig Joseph Maximilian von Starhemberg (Paris, 12 March 1762 – Dürnstein, Lower Austria, 2 September 1833) was an Austrian diplomat and since 1802 Knight of the Order of the Golden Fleece.

After a further professional stay as Envoy in Turin (1805–1810), he withdrew completely into private life, temporarily living in Eferding.

He married in Brussels in 1781 Princess Marie Luise Franziska von Arenberg (1764–1835), daughter of Field Marshal Duke Charles Marie Raymond, 5th Duke of Arenberg and his wife, Countess Louise Margarethe von der Marck-Schleiden (1730–1820).

When his father's older brother, Count Ernst von Starhemberg, died childless, he inherited the dominions of Schaunberg, Eferding and Wagenberg in Upper Austria.

In Vienna he joined the Masonic lodge Zur Neugekrönte Hoffnung, which also included Emanuel Schikaneder and Wolfgang Amadeus Mozart.
