Kopper's Hotel and Saloon, also known as the Airedale Building, is a National Register of Historic Places listed building in Denver, Colorado. It was designed by Frederick C. Eberley. The Hotel and Saloon was constructed in 1889. The building was renamed the Airedale in 1919 and the pediment was modified accordingly. The facade is not believed to have undergone any other major changes at the time. The building is an example of Queen Anne commercial style architecture. The first floor has been extensively remodeled, but the upper floors remain largely intact.
