The Sulm is a river in the Heilbronn district of Baden-Württemberg, Germany. It is an unnavigable right tributary of the Neckar. It rises in the Löwenstein Mountains and after distance and elevation drop flows into the Neckar at Bad Friedrichshall, near Untereisesheim and Neckarsulm. Its valley together with its tributary valleys is also known as the Weinsberg Valley (Weinsberger Tal), after Weinsberg, which is located there. The medieval region of Sulmgau, as well as the city of Neckarsulm, were named for it. The upper valley of the Sulm is a protected area.
