Marte Vallis is a valley in the Amazonis quadrangle of Mars, located at 15 North and 176.5 West. It is 185 km long and was named for the Spanish word for "Mars".[2] It has been identified as an outflow channel, carved in the geological past by catastrophic release of water from aquifers beneath the Martian surface.[3]

Marte Vallis is the site of the first discovery of columnar jointing on Mars.[1]
