Cerro Nicholson is a scoria cone in Peru. It is constructed on top of the 1.65 mya Arequipa Airport Ignimbrite and is well preserved with a summit crater. It is located west-southwest of Chachani volcano[1] and was emplaced 77,400 ± 18,400 years ago.[2]

It is part of the so-called "Yura Monogenetic Field", which was only discovered in 2022.[2] Lavas erupted from this centre are dark in colour. They are basalt andesitic with vesicularity between 0 and 70%.[3]
