Standard Oil Building, also known as the Stanbalt Building, is a historic office building located at Baltimore, Maryland, United States. It is a 15-story Beaux Arts skyscraper designed by Clyde N. Friz (1867-1942), one of Baltimore's best-known Beaux Arts designers, and built in 1922. The steel-frame U-shaped office building is clad in limestone. It was built by the Standard Oil Company at a time when that business was once one of the nation's principal corporations, the dominant supplier of gasoline and fuels.
