Kopper's Hotel and Saloon, also known as the Airedale Building, is a National Register of Historic Places listed building in Denver, Colorado.

The saloon closed down due to statewide prohibition and the property was sold by its German owner (Albert Kopper, a Bavarian immigrant) at a time when anti-German sentiment was strong during World War I.

The building is an example of Queen Anne commercial style architecture.

Many of the bars were located along Market St. and Larimer St. to the southwest of Kopper's Saloon.
