Noachis Terra (lit. "Land of Noah") is an extensive southern landmass (terra) of the planet Mars. It lies west of the giant Hellas impact basin, roughly between the latitudes −20° and −80° and longitudes 30° west and 30° east, centered on 45°S 350°E / 45°S 350°E / -45; 350Coordinates: 45°S 350°E / 45°S 350°E / -45; 350. It is in the Noachis quadrangle.

The term "Noachian epoch" is derived from this region.

Coloring of the base map indicates relative elevations, based on data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor. Reds and pinks are higher elevation (+3 km to +8 km); yellow is 0 km; greens and blues are lower elevation (down to −8 km). Whites (>+12 km) and browns (>+8 km) are the highest elevations. Axes are latitude and longitude; Poles are not shown.
