Ceratonia oreothauma is a species of tree native to Oman and Somaliland.

Ceratonia oreothauma is a small tree with gnarled branches and rough bark which grows up to 8 meters high.

oreothauma is found in a single valley on Jebel Aswad in the eastern Hajar Mountains of Oman between 900 and 2000 meters elevation.

The eastern portion of its population is in Wadi Siren Nature Reserve.

In addition the pollen grains of C. oreothauma are slightly smaller than those of C. siliqua and are tricolporate rather than tetracolporate.
