Pima County Courthouse, Spanish Colonial Revival courthouse in downtown Tucson, United States.

The Pima County Courthouse is a former main county courthouse in downtown Tucson, Arizona, designed by Roy Place in 1928 in Mission Revival and Spanish Colonial Revival styles. It is listed on the National Register of Historic Places and now houses the Southern Arizona Heritage & Visitor Center.

Architect Roy Place designed this courthouse in 1928, with construction completed in 1930. The building then served as the Pima County Superior Court until 1977, when it transitioned to other uses.

The courthouse now holds the Southern Arizona Heritage & Visitor Center, and the University of Arizona Mineral Museum began moving there from the university campus in 2020. The building's former courtrooms and offices were being converted for museum use, with the county in talks with the University of Arizona and the Tucson Museum of Art about exhibits.

The courthouse stands in downtown Tucson at the corner of West Congress Street, with the Superior Court now at 110 West Congress Street and the Consolidated Justice Court at 240 North Stone Avenue. The Southern Arizona Heritage & Visitor Center occupies the building, so start there for orientation before viewing the exhibits.

Inside the building stands a memorial honoring victims of the 2011 Tucson shooting, an event that also injured U.S. Representative Gabby Giffords. This tribute marks an important moment in the community's recent past.
