Colorado Springs City Auditorium, Multi-purpose hall in Colorado Springs, United States.

The Colorado Springs City Auditorium is a multi-purpose hall completed in 1923 at a cost of $424,910. Above the stage, a plaque reads "USUI CIVIUM DECORI URBUS", meaning "For the use of the people and the glory of the city." The building has hosted concerts, theatre performances, graduations, boxing and wrestling matches, and the Harlem Globetrotters.

The building was completed in 1923 as a result of collaboration between architects Thomas MacLaren, Charles Thomas, and Thomas Hetherington. It was created to meet the city's need for a modern event venue that could serve a growing community.

Two notable murals from the Works Progress Administration era adorn the lobby, showing mining scenes and performance art themes created by local artists Archie Musick and Tabor Utley. These artworks tell the story of the region's past and the importance of performing arts to the community.

The auditorium stands in downtown Colorado Springs and hosts events throughout the year. The Pikemasters Model Railroad club meets in the basement, in the old police firing range, on Thursday nights and welcomes visitors.
