Leon Solomon Moisseiff (November 10, 1872 – September 3, 1943) was a leading suspension bridge engineer in the United States in the 1920s and 1930s. He was awarded The Franklin Institute's Louis E. Levy Medal in 1933.

His developments of the theory of suspension bridges are eclipsed by the dramatic failure of the Tacoma Narrows Suspension Bridge, his design, four months after its completion in 1940. The event was filmed and is shown to engineering students as a reminder of the possibility of failure and the importance of avoiding hubris.
