'''Crary Mountains''' ({{coord|76|48|S|117|40|W|name=Crary Mountains}}) are a group of ice-covered volcanoes in [[Marie Byrd Land]], [[Antarctica]]. They consist of two or three [[shield volcano]]es, named [[Mount Rees (Marie Byrd Land)|Mount Rees]], [[Mount Steere]] and [[Mount Frakes]], which developed during the course of the [[Miocene]] and [[Pliocene]] and last erupted about 30,000-40,000 years ago. The first two volcanoes are both heavily incised by [[cirque]]s, while Mount Frakes is better preserved and has a {{convert|4|km}} wide [[caldera]] at its summit. [[Boyd Ridge]] is another part of the mountain range and lies southeast of Mount Frakes; it might be the emergent part of a platform that underlies the mountain range.

The volcanoes consist mainly of [[basalt]], [[trachyte]] and [[phonolite]] in the form of [[Lava|lava flows]], [[scoria]] and [[Hydrovolcanic eruption|hydrovolcanic]] formations. Volcanic activity here is linked to the [[West Antarctic Rift System|West Antarctic Rift system]], which is responsible for the formation of a number of volcanoes in the region. During their existence, the range was affected by glaciation and glacial-volcanic interactions.
