The SUNY System Administration Building, also known as the Old D&H Railroad Building, is a public office building located at the intersection of Broadway and State Street in downtown Albany, New York. Locally the building and land it sits on is referred to as State University Plaza, or the D&H Plaza; prior to the construction of the Empire State Plaza it was simply "The Plaza". It was listed on the National Register of Historic Places in 1972 as Delaware and Hudson Railroad Company Building. In 1980, when the Downtown Albany Historic District was listed on the Register, it was included as a contributing property.
The central tower is thirteen stories high and is capped by an 8-foot-tall (2.4 m) working weathervane that is a replica of Henry Hudson's Half Moon. The State University of New York is centrally administered from this location. The southern tower's four top floors are the official residence of the Chancellor of SUNY.
