The Galva Opera House is a historic theater located at 334-348 Front Street in Galva, Illinois. Built in 1878, the theater opened as the Blue Ribbon Temperance Hall; by 1886, it had lost its association with the temperance movement and was known by its present name. Galva's location on two major railroad lines allowed traveling theatrical troupes to visit the theater; shows produced by local talent performed in the building as well. Local schools also used the building for their graduation ceremonies, sporting events, and school plays until Galva High School opened its own auditorium in 1932. The building was used as a roller skating rink in the 1920s and 1930s and hosted Lions Club events in the 1950s.
