TheNanedi Valles are a set of channels in a large valley in theLunae Palus quadrangle ofMars, located at 4.9° N and 49.0° W. They are 508 km long and were named for the word for "planet" inSesotho, the national language ofLesotho, Africa.[1]

The Nanedi Valles are located betweenShalbatana Vallis and the upperMaja Valles. They are 4 km wide at their northern end. Their valley's shape is similar to that ofNirgal Vallis, being very sinuous and having only a few short branches.[2]

Unusually for Martian valleys, the individual channel structures within the wider valley floors can occasionally be seen in this system.[3]
