Charles (German: Karl Friedrich Alexander, König von Württemberg; 6 March 1823, Stuttgart – 6 October 1891, Stuttgart) was the third King of Württemberg, from 25 June 1864 until his death in 1891.

He was born 6 March 1823 in Stuttgart, as HRH Charles Frederick Alexander, Crown Prince of Württemberg the son of William I, King of Württemberg (1781–1864) and his third wife (and first cousin) Pauline Therese of Württemberg (1800–1873).

He studied in Berlin and Tübingen.

On 13 July 1846 he married Grand Duchess Olga Nikolaievna of Russia, daughter of Tsar Nicholas I and Charlotte of Prussia. Charlotte was a daughter of Frederick William III of Prussia and Louise of Mecklenburg-Strelitz. She took the name Alexandra upon her marriage. Karl acceded to the throne upon his father's death in 1864.

The couple had no children, perhaps because of Karl's homosexuality. Karl became the object of scandal several times for his closeness with   various men. The most notorious of these was the American Charles Woodcock, a former chamberlain whom Karl elevated to Baron Savage in 1888. Karl and Charles became inseparable, going so far as to appear together   in public dressed identically. The resulting outcry forced Karl to   renounce his favorite. Woodcock returned to America, and Karl found   private consolation some years later with the technical director of the   royal theater, Wilhelm George.

In 1870, Olga and Karl adopted Olga's niece Vera Konstantinova, the daughter of her brother Grand Duke Konstantin.

Under Charles' leadership, in 1871 Württemberg became a part of the German Empire.

He died, childless, in Stuttgart on 6 October 1891, and was succeeded as King of Württemberg by his sister's son, William II. He is buried, together with his wife, in the Old Castle in Stuttgart.
