The Jeffersonian Apartments—currently branded as “The Jefferson”—is a large apartment building at 9000 East Jefferson Avenue, on the near-east side of Detroit, Michigan. Built in 1965, primarily of glass and steel in the international architecture style, it is one of Detroit's tallest residential buildings -- standing 30 stories with 412 residential units.
The site is close to the MacArthur Bridge and Belle Isle. As the building is situated on a steep slope, the Jefferson Avenue entrance is 17 feet higher than the back entrance along the Detroit River.
