Polly Rosenbaum Building, Moorish Revival building in Phoenix, Arizona.

The Polly Rosenbaum Building is an Exotic Revival/Moorish Revival building at the corner of 15th Avenue and Washington Street in Phoenix, Arizona. Completed in 1921, it was designed by Lescher & Mahoney and built by Clinton Campbell, and covers 18,000 square feet (1,700 m2) on a 0.8-acre property. It was listed on the National Register of Historic Places in 1989 as the El Zaribah Shrine Auditorium.

The building was constructed in 1921 and originally served as El Zaribah Shrine Auditorium for local Shrine gatherings. It later received its current name to honor a legacy of advocacy related to mining and mineral development in the state.

The building's name honours Polly Rosenbaum, a long-serving member of the Arizona House of Representatives who, with Governor Rose Mofford, pushed to acquire and renovate it as a permanent home for the state's mineral collection and archives. A second state building in Phoenix, the Polly Rosenbaum State Archives and History Building at 19th and Madison, completed in 2008, also carries her name.

The building stands at the corner of 15th Avenue and Washington Street and is easy to locate. Visitors should check ahead before visiting, as access times may be limited.
