The Württemberg Class B and Class B2 engines were steam locomotives with the Royal Württemberg State Railways (Königlich Württembergische Staats-Eisenbahnen) first built in 1868 by the Maschinenfabrik Esslingen ('Esslingen engineering works') in Esslingen in the former Kingdom of Württemberg in southern Germany.

The engines had a Crampton boiler, an inside Allan valve gear and, for the first time in Württemberg, a Prüsmann chimney. They were equipped with 2 T 6.5 tenders.
