Frederick Louis of Nassau-Ottweiler (13 November 1651 in Ottweiler – 25 May 1728 in Saarbrücken) was a member of the House of Nassau.
He was the son of John Louis, Count of Nassau-Ottweiler and Countess Palatine Dorothea Catherine of Birkenfeld-Bischweiler. He was count of Nassau-Ottweiler from 1680 until his death. From 1721, he was also Count of Nassau-Idstein; from 1723 also Count of Nassau-Saarbrücken. Because he had no male heir, his territories fell to his cousin Charles of Nassau-Usingen after his death in 1728.
Frederick Louis married on 28 July 1680 with Christiane (1659-1695), the daughter of Frederick of Ahlefeldt and Margaret Dorothea of Rantzau. They had eight daughters:
After Christiane's death, Frederick Louis married on 27 September 1697 Countess Louise Sophie of Hanau-Lichtenberg (11 April 1662 in Bischofsheim am Hohen Steg – 9 April 1751 in Ottweiler), the daughter of Johann Reinhard II of Hanau-Lichtenberg and Countess Palatine Anna Magdalena of Birkenfeld-Bischweiler. This marriage remained childless.
