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.
