Chimborazo (Spanish pronunciation: [tʃimboˈɾaso]) is a currently inactive stratovolcano located in the Cordillera Occidental range of the Andes. Its last known eruption is believed to have occurred around 550 AD.

With a peak elevation of 6,268 metres (20,564 ft), Chimborazo is the highest mountain in Ecuador. It is the highest peak in close proximity to the equator. While Chimborazo is not the highest mountain by elevation above sea level, its location along the equatorial bulge makes its summit the farthest point on the Earth's surface from the Earth's center.
