Crown Prince Friedrich Ludwig

Frederick Louis of Württemberg (Stuttgart, 14 December 1698 - Ludwigsburg, 23 November 1731) was heir to the duchy of Württemberg.

He was the only son of Duke Eberhard Ludwig and Johanna Elizabeth, daughter of Margrave Frederick VII of Baden-Durlach.

Friedrich Ludwig, however, died before his father, who survived him until 1733. With his death, without male heirs, the main line of Württemberg became extinct and the duchy passed to a collateral line of Württemberg-Winnental.

On December 8, 1716, Frederick Louis, married Henrietta Maria, daughter of Margrave Philip William of Brandenburg-Schwedt, with whom he had children:

1. Eberhard Friedrich (1718–1719)

2. Louisa Friederike (3 February 1722 – 2 August 1791), who married Duke Friedrich II of Mecklenburg-Schwerin
