The Carson City Post Office is an historic building in Carson City, Nevada built during 1888-1891. It was designed by architect Mifflin E. Bell. It was listed on the National Register of Historic Places in 1979.
It is significant as the first Federal building built in Nevada, and the only one of its architectural style, which is Richardsonian Romanesque. It served as a courthouse of the United States District Court for the District of Nevada from 1891 to 1965. It was renamed the Paul Laxalt State Building, for former Nevada Governor Paul Laxalt, in 1999, and now houses the Nevada Commission on Tourism.
Bell, a Supervising Architect of the Treasury Department, was the initial architect, while work was completed under Supervising Architect successors Will Frost and James Windrum.
