Juglans regia, the common walnut[1] or Persian walnut[2] amongst other regional names, is a species of walnut. It is native to Eurasia in at least southwest and central Asia and southeast Europe, but its exact natural area is obscure due to its long history of cultivation.

The species has numerous cultivars which produce the edible walnut consumed around the world and produced predominately in China. It is widely cultivated across temperate regions throughout the world including those of Eurasia, Australia, and the Americas.
