The Muksu ({{langx|ru|Муксу}}, {{langx|tg|Муқсу}} Muqsu) is a west-flowing river in northeastern Tajikistan. It is a tributary of the Vakhsh which in turn is a tributary of the Amu Darya. The river is {{convert|88|km|mi}} long and has a basin area of {{convert|7070|km2|mi2}}.[http://bse.sci-lib.com/article078944.html Муксу], Great Soviet Encyclopedia It is formed at the confluence of the rivers Seldara (draining the Vanch-Yakh Glacier) and Sauksay (draining the Saukdara Glaciers), near Altyn Mazar. The north side of its valley is the Trans-Alay Range and the south side is formed by the Peter I Range and the Academy of Sciences Range. It joins the Kyzyl-Suu (which drains the Alay Valley) to form the Surkhob or Vakhsh. At Altyn Mazar there is a pass leading north to Daroot-Korgon in the Alay Valley.
