|Quadrangle||Margaritifer Sinus quadrangle|
Iazu is an impact crater located within the Meridiani Planum extraterrestrial plain, situated within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars. This geological feature is about 7 km in diameter. It is close to the landing site of the Mars Exploration Rover-B Opportunity, and its walls have been photographed by the spacecraft during its traverse to Endeavour Crater. At the time, the crater was about 38 kilometers (24 mi) away. It was named in 2006 for Iazu, a commune in Dâmboviţa County, southern Romania.
Bopolu (crater) is west of Iazu and Endeavour crater.
