Kasei Valles je ohromný systém kaňonů v oblasti Mare Acidalium a Lunae Palus na Marsu. Ohromný systém je rozšířen až po 300 mil, jedná se o jeden z nejdelších odtokových kanálů na povrchu Marsu. Kasei Valles počíná u Echus Chasma poblíž systému Valles Marineris, dále vede na sever a směřuje do Chryse Planitia, nedaleko od místa přistání sondy Viking 1. Ohromné údolí Kasei Valles se dělí na dvě větvě, které obepínají ostrov, nazývaný Sacra Mensa. Některé části Kasei Valles jsou až 2 - 3 km hluboké. Pravděpodobný původ údolí je vytvoření tekutou vodou razící si cestu po povrchu planety, po zahřátí oblasti vulkanickou činností. Dokonce se objevují i spekulace o možném pohybu ledovců na Marsu, i když nejsou přímé důkazy.

Kasei Valles cataracts.jpg
View of a portion of the Kasei Valles system of outflow channels in the region immediately southwest of the 100 km diameter martian crater Sharonov (partly visible at upper right). In this area of Kasei Valles there are three putative cataracts (dry falls) created by the megafloods that formed the channels.

This scene is a section of a larger THEMIS daytime infrared image mosaic of Kasei Valles. Kasei Valles is situated north of the Valles Marineris canyon system and drains eastward into Chryse Planitia. North is at the top.
