Caxias is a Martian impact crater, approximately 25 kilometers in diameter. It is located at 29.3°S, 100.8°W, southeast of the crater Llanesco and northeast of the crater Dinorwic. It was named after Duque de Caxias, a town in Brazil, and its name was adopted by the International Astronomical Union in 1991. According to a surface age map of Mars based on US Geological Survey data, the area around Caxias is from the Noachian or Hesperian epoch, which places the area's age at 3.8 to 1.8 billion years. The crater is about 7,400 meters in elevation above zero altitude on its floor, and averages about 8,000 meters above zero altitude on its rim; it is therefore about 600 meters in depth.
