The St. George Opera House, also known as the St. George Social Hall, is a historic building in St. George, Utah. It was originally built by the St. George Gardeners' Club as a wine cellar. As wine demand decreased, the building was expanded to host theatrical productions. It operated in this capacity until sold to the Utah-Idaho Sugar Company in 1936. It was restored to an opera house in 1988 and is again open to the public.
