Engelmann Peak, Mountain summit in Empire, Colorado, United States.

Engelmann Peak is a 13,368-foot (4,075 m) mountain summit in the Front Range of the Rocky Mountains, located in Arapaho National Forest, 6.3 miles west by south of Empire in Clear Creek County, Colorado. The mountain was named in honor of the botanist George Engelmann.

The peak was named after botanist George Engelmann, who traveled to America in 1832 to study Rocky Mountain plant life. This naming honors his contributions to documenting and classifying North American plant species.

The peak carries the name of George Engelmann, the German-born botanist who described and named much of the Rocky Mountain flora. He earned his medical degree in Germany before sailing to America in 1832, backed by relatives who wanted him to invest in land; he explored Illinois, Missouri and Arkansas. The mountain was also recorded earlier as Cowles Mountain, and the Engelmann Peak form was in use by 1912.

The summit lies in Arapaho National Forest, 6.3 miles west by south of Empire in Clear Creek County, reached via the Ruby Creek approach. The 13,368-foot elevation and 542-foot prominence mean a long, steep day; carry mountain gear and check conditions before setting out. Snow can linger on upper slopes outside summer and early fall.

The peak was earlier recorded as Cowles Mountain and appears as Englemann Peak in 1912 records, a spelling variant of today's name. It rises 6.3 miles west by south of the Town of Empire in Clear Creek County, within Arapaho National Forest.
