 The Arcadia quadrangle is one of a series of 30 quadrangle maps used by the United States Geological Survey (USGS). The quadrangle is located in the northern hemisphere of Mars  and covers 30° to 65° north latitude and 60° to 120° west longitude (300° to 240° east longitude). The Arcadia quadrangle is also referred to as MC-3 (Mars Chart-3).<ref>Davies, M.E.; Batson, R.M.; Wu, S.S.C.

-Arcadia is the name of a classical albedo feature  located at 45° north latitude and 260° east longitude on Mars. The feature was named after a mountainous region in southern Greece.<ref>Blunck, J.  1982.  Mars and its Satellites.  Exposition Press.  Smithtown, N.Y.</ref>  The name was approved by the International Astronomical Union(IAU) in 1958.<ref>USGS Gazetteer of Planetary Nomenclature.
