The flag of the United States Navy consists of the Seal of the Department of the Navy in the center, above a yellow scroll inscribed "United States Navy" in dark blue letters, against a dark blue background.

The flag was officially authorized by President Dwight D. Eisenhower on April 24, 1959 and was formally introduced to the public on April 30, 1959 at a ceremony at Naval Support Facility Carderock in Maryland. It replaced the Infantry Battalion flag which had been used as the unofficial Flag of the United States Navy for many years.
