The Metropolitan Life North Building, now known as Eleven Madison, is a 30-story Art Deco skyscraper adjacent to Madison Square Park at 11–25 Madison Avenue in the Flatiron District neighborhood of Manhattan in New York City. The building is bordered by East 24th Street, Madison Avenue, East 25th Street and Park Avenue South, and was formerly connected by a sky bridge and tunnel to the Metropolitan Life Insurance Company Tower just south of it.

The North Building was built in three stages on the site of the second Madison Square Presbyterian Church. Construction started in 1929, just before the onset of the Great Depression. Originally planned to be 100 stories, the North Building was never completed as originally planned due to funding problems following the Depression. The current design was constructed in three stages through 1950. As part of the Metropolitan Life Home Office Complex, the North Building was added to the National Register of Historic Places on January 19, 1996.^[1]
