The Lunae Palus quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. Lunae Planum and parts of Xanthe Terra and Chryse Planitia are found in the Lunae Palus quadrangle. The Lunae Palus quadrangle contains many ancient river valleys.
The quadrangle covers the area from 45° to 90° west longitude and 0° to 30° north latitude on Mars. The Viking 1 Lander (part of Viking program) landed in the quadrangle on July 20, 1976, at 22.4°N 47.5°W.
