萨赫勒（阿拉伯语：ساحل‎，意为“边缘”）是非洲北部撒哈拉沙漠和中部苏丹草原地区之间的一条长超过3,800千米的地带，从西部大西洋伸延到东部非洲之角，横跨塞内加尔、毛里塔尼亚、马里、布基纳法索、尼日尔尔、尼日尔利亚、乍得、苏丹共和国和厄立特里亚9个国家。一说萨赫勒现还伸展扩张至埃塞俄比亚和索马里境内。有人说这里是班图人发源地。

萨赫勒是半干旱的草原地区，具有从典型的热带草原向撒哈拉沙漠过渡的地理特点，年降水量从北向南约为200至600毫米。

萨赫勒地区的人民主要从事农牧业。

The Sahel (/səˈhɛl/) is the ecoclimatic and biogeographic zone of transition in Africa between the Sahara Desert to the north and the Sudanian Savanna to the south. Having a semi-arid climate, it stretches across the south-central latitudes of Northern Africa between the Atlantic Ocean and the Red Sea. The Arabic word sāḥil (ساحل) literally means "shore, coast", describing the appearance of the vegetation found in the Sahel as being akin to that of a coastline delimiting the sand of the Sahara.
