Casablanca-Settat (Arabic: الدار البيضاء - سطات, romanized: ad-dār al-bayḍāʾ - siṭṭāt) is one of the twelve administrative regions of Morocco.

Part of the border with Marrakesh-Safi follows the course of the Oum Er-Rbia River, which flows northwest and empties into the Atlantic at Azemmour.

Several reservoirs provide water for the region, including that of the Al Massira Dam on the Oum Er-Rbia and one on the Oued Mellah south of Mohammedia.

[3] Mustapha Bakkoury, a member of the Authenticity and Modernity Party, was elected as the first president of Casablanca-Settat's regional council on 14 September 2015.

Railways link the region with Marrakesh to the south, Oued Zem to the southeast, and Rabat and other Moroccan cities to the northeast.
