Philippsburg (German pronunciation: [ˈfɪlɪpsbʊʁk] ⓘ) is a town in the district of Karlsruhe, Baden-Württemberg, Germany.

The town is named after Philipp Christoph von Sötern,[3] who was bishop from 1610–1652.

Historically, possession of the town was disputed between Germany and France.

In Book VI of On War, he suggested that "If a fortress cannot be located directly on a river, it is better not to place it in the immediate vicinity, but some fifty to sixty miles away; otherwise the river will cut through and interfere with its sphere of influence with respect to all the points mentioned above."

The siege of Philippsburg is covered in Clausewitz's campaign history.
