法属苏丹（法文：Soudan），是法属西非内的一个殖民地。前后共分为1890年至1902年及1920年（自上塞内加尔和尼日尔尔殖民地分立）至1960年两个时期，直到该地区独立改为马利为止。

为了同英埃苏丹作出区别，法属苏丹被称作西苏丹，英埃苏丹为东苏丹，直至1960年。

French Sudan (French:Soudan Français; Arabic:السودان الفرنسي‎ as-Sūdān al-Faransī) was a French colonial territory in the federation of French West Africa from around 1880 until 1960, when it became the independent state of Mali. The colony was formally called French Sudan from 1890 until 1899 and then again from 1920 until 1958, and had a variety of different names over the course of its existence. The colony was initially established largely as a military project led by French troops, but in the mid-1890s it came under civilian administration.
