Zamboanga Peninsula (Cebuano: Lawis sa Zamboanga.; Chavacano: Peninsula de Zamboanga; Filipino: Tangway ng Zamboanga) is an administrative region in the Philippines, designated as Region IX. It consists of three provinces (Zamboanga del Norte, Zamboanga Sibugay and Zamboanga del Sur) including four cities (Dapitan, Dipolog, Pagadian, Isabela) and the highly urbanized Zamboanga City. The region was previously known as Western Mindanao before the signing of Executive Order No. 36 of 2001. The city of Zamboanga was designated as the regional center until Pagadian was designated as its new regional center, although Zamboanga City remains the region's cultural, commercial, economic, and educational center.
