Fantale (also spelled Fantalle or Fantala) is a large stratovolcano in the Ethiopian Rift Valley west of Lake Awash. It contains a large spectacular summit caldera. Fantale's historic eruptions produced lava flows that descended to the east side into the valley and lake Awash. An eruption during the 13th century destroyed a town and church located south of the volcano. In 1820, a 4 km long fissure eruption occured on the east flank and sent basaltic lava flows both into the caldera and outside, reaching the bottom of the Rift valley.

Fantale is known for welded ash flows thought to correspond to violent eruptions that were followed by the formation of its 2.5 x 4.5 km summit caldera surrounded by steep walls up to 500 m high. The volcano was built on a WNW-ESE-trending orientation perpendicular to the axis of Ethiopian Rift and flank vents exist on the same line.
