Frenchman Mountain is located east of Las Vegas, Nevada, United States. It is not part of any mountain range. Comprised of rocks similar to those found on the bottom of the Grand Canyon, Frenchman Mountain formed when faulting elevated it, giving it its sharp triangulated slope. It is the site of the Great Unconformity. It is capped by Vishnu Schist rock, which is some of the oldest rock on the earth, having been created about two billion years ago.

Nevada State Route 147 crosses its northern slope. A geologically rich area called Rainbow Gardens is located to its southeast, as is a cinder cone, Lava Butte.

It is commonly, and mistakenly, referred to as Sunrise Mountain, the name of a smaller peak to the north of Frenchman Mountain. The area between Charleston Boulevard and Las Vegas Boulevard east of Lamb Boulevard is commonly known as the Sunrise Mountain Area.
