Parana Valles is a valley in the Margaritifer Sinus quadrangle (MC-19) region of Mars, located at approximately 23.1° South and 10.2° West. It is 350 km long and was named after an ancient and modern name for a South American river (Brazil, Argentina). A low area between Parana Valles and Loire Vallis is believed to have once held a lake.
