Manchuria is a modern name given to a large geographic region in Northeast Asia. Depending on the definition of its extent, Manchuria usually falls entirely within China, or is sometimes divided between China and Russia. The region is now usually referred to as Northeast China in China although "Manchuria" is widely used outside of China to denote the geographical and historical region. This region is the traditional homeland of the Xianbei, Khitan, and Jurchen peoples, who built several states historically. (The Jurchen, later called the Manchus, are those after whom Manchuria is named.)
