Robert Anton Young III (November 27, 1923 – October 17, 2007) was a Democratic politician from the state of Missouri who served five terms in the US House of Representatives.

Young's long political career began in 1952 with his election as Democratic Committeeman for Airport Township in St. Louis County, an office he held until 1977.

During his years in the State Legislature, Young supported legislation that created the St. Louis Junior College District and helped establish the University of Missouri–St.

As a member of Congress, he served on several key committees including Public Works and Transportation, Aviation, Water Resources, and Science and Technology.

Young was a strong proponent of public works projects to benefit his district and the state of Missouri.

Among the projects he supported were landscaping the Gateway Arch, renovation of the Old Post Office, the creation of the light-rail mass transit MetroLink system, the construction of the Thomas F. Eagleton Federal Courthouse, the expansion of Lambert Airport, and the new Lock and Dam 26 at Alton, Illinois.

Originally named the St. Louis Mart and Terminal Warehouse, the Art Deco building at 1222 Spruce Street was designed by Preston J. Bradshaw and completed in 1933.
