Menabe is a region in western Madagascar, with its capital at Morondava. It covers an area of 46,121 square kilometres (17,807 square miles), and its population was estimated to be 592,113 in 2013. The population mostly belongs to the Sakalava ethnic group. The region is named after the 18th-century Sakalava Kingdom of Menabe (16th-18th centuries). The name "Menabe", in turn, means "big red", after the color of laterite rock that dominates the landscape.
