The Eridania quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Eridania quadrangle is also referred to as MC-29 (Mars Chart-29).

The Eridania quadrangle lies between 30° and 65° south latitude and 180° and 240° west longitude on the planet Mars. Most of the classic region named Terra Cimmeria is found within this quadrangle. It is named after a region on the Po River, Italy. The name was approved by the IAUP in 1958.

Part of the Electris deposits, a 100–200 meters thick, light-toned deposit covers the Eridania quadrangle. Many slopes in Eridania contain gullies, which are believed to be caused by flowing water.
