Berrian Mountain is a mountain summit in the Front Range of the Rocky Mountains of North America. The 9,151-foot (2,789 m) peak is located 0.9 miles (1.5 km) north-northeast (bearing 17°) of the community of Aspen Park in Jefferson County, Colorado, United States.

According to Jefferson County Archives, Berrian Mountain was named after George, Dan, and Ray Berrian and the Berrian family who came from Kansas to Colorado in 1887. Previously, it may have been called McIntyre Mountain after Duncan McIntyre, who owned property on the east side of the mountain where Midway House is located.
