Nighthawks (1942) is a painting by Edward Hopper that portrays people sitting in a downtown diner late at night. It is not only Hopper's most famous painting, but also one of the most recognizable in American art. It is currently in the collection of the Art Institute of Chicago.
"Nighthawks" may be Hopper's take on the term night owl used to describe someone who stays up late. The scene was inspired by a diner (since demolished) in Greenwich Village, Hopper's home neighborhood in Manhattan. The now-vacant lot is known as Mulry Square, at the intersection of Seventh Avenue South, Greenwich Avenue, and West 11th Street.
