The Herrenwieser See is a tarn in the municipality of Forbach in the Northern Black Forest in Germany.

It lies at a height of 830 metres, a little northwest of the Schwarzenbach Reservoir and 1,600 metres as the crow flies northeast of Herrenwies on the eastern mountainside of the 1,001-metre-high Seekopf, a subpeak of the Badener Höhe.

Habitats Directive area and, together with the cirque headwall, designated as a biotope.

The lake itself is surrounded by a fence and the shore is out-of-bounds for nature conservation reasons.

In the days of timber rafting a facility was built that enabled logs to be transported down the valley on the waters from the lake.
