Schwarzwald-Baar (German pronunciation: [ˌʃvaʁtsvaltˈbaːɐ̯]) is a Landkreis (district) in the south of Baden-Württemberg, Germany.

Neighboring districts are (from north clockwise) Ortenaukreis, Rottweil, Tuttlingen, Constance, the Swiss canton of Schaffhausen, and the districts Waldshut, Breisgau-Hochschwarzwald and Emmendingen.

The Black Forest (Schwarzwald), and the Baar, the foothills between the Black Forest and the Swabian Jura (Schwäbische Alb).

The eagle in the top-left quarter is taken from the coat of arms of the city of Villingen, and derives from the Zähringen family who ruled that city in the 13th century.

When the cities of Villingen and Schwenningen merged to form Villingen-Schwenningen in 1972, a similar method was used to derive a new city coat of arms.
