The Bass Building is a historic building located at 119 St. Patrick in Tonopah, Nevada. Built in 1904, the building is the third oldest stone commercial building in Tonopah. The building has a simple stone design reflective of a transitional period between rustic and well-crafted stone buildings. A. A. Bass built the structure as a lodging house; it later served as offices for a telephone company and as a fraternal lodge. A 1912 fire gutted the building's interior, but Bass rebuilt it the following year.

The building was added to the National Register of Historic Places on May 20, 1982.
