Boller Brothers, also spelled as Boller Bros., was an architectural firm based in Kansas City, Missouri which specialized in theater design in the Midwest of the United States during the first half of the 20th century. Carl Heinrich Boller (1868–1946) and Robert Otto Boller (1887–1962) can be credited with the design of almost 100 classic theaters ranging from small vaudeville houses to grand movie palaces. About 20 Boller Brothers works are listed on the National Register of Historic Places.
