The Alzou is a short river in the Lot département, southern France, a right tributary of the Ouysse. It flows through the town Rocamadour, and joins the Ouysse, itself a left tributary of the Dordogne, downstream of Rocamadour. The valleys of both the Alzou and the Ouysse are deep limestone canyons.
