Dornhan was first mentioned in a document as "Turnheim" in 777, but the exact date of its becoming a town is unknown, although it is certain that the place has been called "civitas" (town) since 1276.
The town of Dornhan originally belonged to the Grafen von Sulz. 1095 the Alpirsbach Monastery received estates located in Dornhan by donation. The monastery gained more and more influence in Dornhan in the course of time and maintained a nursing home to administer the property. The abbot of Alpirsbach monastery had a court held in Dornhan three times a year, either personally or through a deputy. However, the monastery was only responsible for cases with lower jurisdiction, the high juristiction was the responsibility of the dukes of Teck, who held the hereditary bailiwick rights of the monastery. Because of his high debts, Duke Friedrich von Teck ceded the bailiwick rights to Count Eberhard den Greiner in 1380 and thus to Württemberg. From this time on, a Württemberg sheriff exercised the sovereign rights.  With the reformation of the Alpirsbach monastery in 1534, Dornhan finally fell to Württemberg and was since then the seat of a Württemberg bailiff as the office of Dornhan until 1807.
During the administrative reform in during the NS period in Württemberg Dornhan came to the district of Horb in 1938. After the Second World War, the town of Dornhan fell into the French occupation zone and thus came to the newly founded state Württemberg-Hohenzollern in 1947, which was absorbed into the state of Baden-Württemberg in 1952.
In 1973, the District Reform in Baden-Württemberg took place, in which Dornhan became part of the district of Rottweil.
Today's town was newly formed on 1 March 1972 by merging the town of Dornhan with the communities of Bettenhausen, Fürnsal, Leinstetten and Marschalkenzimmer. On 1 April 1974, the previously independent community of Busenweiler was incorporated. The incorporation of Weiden took place on 1 January 1975.
