Frédéric Maurice Casimir de La Tour d'Auvergne (Frédéric Maurice Casimir; 24 October 1702 – 1 October 1723) styled Prince of Turenne, was the eldest surviving son of Emmanuel Théodose de La Tour d'Auvergne (1668–1730).
His father was the ruler of the Duchy of Bouillon, a small principality in present-day Belgium.
The second of their sons, he was not styled prince de Turenne till his older brother's death (Godefroy Maurice) in 1705 aged just 3.
Having been married in person in Strassburg on 20 September, he died whilst travelling back.
Buried in Münster, his wife of only two months later married his younger brother Charles Godefroy, who, as a result of Frédéric Maurice Casimir's death became Prince of Turenne.
