Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites.
The nomenclature allows up to a few percent of orthopyroxene. Accessory minerals include ilmenite, chromite, magnetite and an aluminium-bearing mineral (plagioclase, spinel or garnet).{{cite web|title=Glossary: Wehrlite|url=https://www2.imperial.ac.uk/earthscienceandengineering/rocklibrary/viewglossrecord.php?gID=00000000094|publisher=Imperial College|accessdate=12 January 2013}}
Wehrlites occur as mantle xenoliths and in ophiolites. Another occurrence is as cumulate in gabbro and norite layered intrusions. Some meteorites can also be classified as wehrlites (e.g. NWA 4797).{{cite web|title=NWA 4797|url=http://curator.jsc.nasa.gov/antmet/mmc/nwa4797.pdf|publisher=curator.jsc.nasa.gov|accessdate=12 January 2013}}
