Tamdoult (also Tamedoult, Tamdlt; Arabic: تامدولت ) was a medieval city located near the Draa river in Morocco south-east of Akka, Morocco. It was an important and flourishing stop in the Trans-Saharan trade route, linking Nul (Asrir) and Ouadane to Sijilmasa, Massa and N'fis. The city was founded in the 9th-century by one of Idriss II sons who had been given a principality in the Sous to reign over the Lamta tribe.
The city and its fortress were allegedly destroyed in the 14th-century by a Marinid King. Today, the shrine of Sidi Mohamed ben Abdallah Ichanaoui is the only surviving structure in the ruins site.
