Duke Maximilian of Württemberg (German: Wilhelm Ferdinand Maximilian Karl Herzog von Württemberg; 3 September 1828, Dischingen – 29 July 1888, Regensburg) was a member and Duke of the royal house of Württemberg.

Duke Maximilian was the only child of Duke Paul Wilhelm of Württemberg and Princess Maria Sophia of Thurn and Taxis, who lived in Württemberg Palace in Regensburg and whose marriage ended in divorce in 1835 after an early separation.^[1] Since the beginning of the 1870s he was the owner of the Württemberg Palace in Regensburg and the associated parks in today's Herzogspark.^{[citation needed]}

Maximilian was a great-nephew of the first King of Württemberg, Frederick. On 16 February 1876 he married Princess Hermine of Schaumburg-Lippe (1845–1930), daughter of Adolf I, Prince of Schaumburg-Lippe. The marriage was childless.^[2] His wife Hermine called herself Duchess Maximilian of Württemberg in Regensburg, in analogy to her mother-in-law, who called herself Duchess Paul of Württemberg after her husband. Hermine was known in Regensburg as an enthusiastic rider who often appeared around the city on horseback in a black riding dress and was popular as a guest in officer circles.^[3]

Like his father and grandfather, he was a Freemason. In 1861 he was accepted into the Masonic lodge "Zu den 3 Cedern" in Stuttgart.^[4]

Since 1851, Maximilian, as Prince of the Royal House, had a mandate in the Württemberg Kammer der Standesherren ("Chamber of Eminents"), the upper chamber of the Estates of Württemberg. Between 1851 and 1870 he occasionally attended the meetings in person. After 1870 he was no longer present in person.^[5]
