The United Electric Co. Building was a historic commercial building at 73 State Street in Springfield, Massachusetts. One of the city's few Beaux-Arts buildings, it was built in 1910 to serve as the headquarters of the United Electric Company, Springfield's supplier of electricity since the 1880s. It was listed on the National Register of Historic Places in 1983. It has been mostly demolished, preserving the facade as part of the MGM Springfield casino project.
