Albor Tholus is an extinct volcano in the volcanic province Elysium on Mars.

It lies south of the neighbouring volcanoes Elysium Mons and Hecates Tholus.

Albor Tholus is 4.5 kilometres[2] high and has a diameter of 160 km[2] at its base.

The elevation of the lowest level of the caldera is the same as the base of the volcano; however, the original lower slopes of Albor Tholus may have been covered by lava flows from its larger neighbor, Elysium Mons.
