Seewald is a municipality in the Freudenstadt district in Baden-Württemberg in southern Germany.

There is a dam in the river near the village Erzgrube, forming the artificial lake Nagoldsee.

The district Besenfeld lies at the middle ground, a distance hiking trail, which passes by many sights.

The lake dams the springing in the district Urnagold River Nagold to a length of about three kilometers.

Since May 2008, the municipality operates a quiet grove, a forest cemetery for alternative forms of burial under trees and glades.
