The Province of Nassau (German: Provinz Nassau) was a province of Prussia from 1944 to 1945.

Although all German states (including Prussia) had been de facto dissolved since 1933, the Nazi government formally partitioned the Prussian province of Hesse-Nassau into two provinces with a decree issued on 1 April 1944 and effective on 1 July 1944. The two new provinces were the province of Kurhessen and the province of Nassau.

The name comes from the former Duchy of Nassau (1806–1866), which Prussia annexed following the Austro-Prussian War to form part of the province of Hesse-Nassau. The territory of the province was larger than that of the former duchy, encompassing those areas of the NSDAP Gau Hesse-Nassau not part of the People's State of Hesse.

Following the end of World War II, most of the province of Nassau fell under American administration. The province of Nassau was dissolved by the occupying US forces on 19 September 1945, forming part of the administrative zone of Greater Hesse along with Kurhessen and the American parts of the People's State of Hesse. Just over a year later, Greater Hesse became the modern German state of Hesse. A small western part of the province of Nassau instead fell under French control; it became the Regierungsbezirk Montabaur of the modern state of Rhineland-Palatinate on 30 August 1946.
