The Midouze (Occitan: Midosa), is a right tributary of the Adour river, in the Landes, in the Southwest of France.

The name Midouze is a portmanteau that fuses the names of the two precursors of the river, the Midou and the Douze.

The Midouze is the union of the Midou (or Midour) and the Douze. These two rivers rise in the Gers département (in the historical region of Armagnac) and join in Mont-de-Marsan. After a course of 43 kilometres (27 mi), the Midouze flows into the Adour downstream from Tartas. It has a length of 151 kilometres (94 mi) from the source of the Midou.
