The Noachis  quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program.
The Noachis  quadrangle is also referred to as MC-27 (Mars Chart-27).

The Noachis quadrangle covers the area from 300° to 360° west longitude and 30° to 65° south latitude on Mars.
 It lies between the two giant impact basins on Mars: Argyre and Hellas.
The Noachis quadrangle includes Noachis Terra and the western part of Hellas Planitia.

Noachis is so densely covered with impact craters that it is considered among the oldest landforms on Mars—hence the term "Noachian" for one of the earliest time periods in martian history.

In addition, many previously buried craters are now coming to the surface, where Noachis' extreme age has allowed ancient craters to be filled, and once again newly exposed.

Much of the surface in Noachis quadrangle shows a scalloped topography where the disappearance of ground ice has left depressions.

The first piece of human technology to land on Mars landed (crashed) in the Noachis quadrangle.
 The Soviet's Mars 2 crashed at 44.2°S 313.2°W.  It weighed about one ton.
 The automated craft attempted to land in a giant dust storm.
 To make conditions even worse, this  area also has many dust devils.
