The seal of the president of the United States is used to mark correspondence from the president of the United States to the U.S. Congress, and is also used as a symbol of the presidency itself. The central design, based on the Great Seal of the United States, is the official coat of arms of the U.S. presidency and also appears on the presidential flag.

The Great Seal is the seal of the United States. The phrase is used both for the impression device itself, which is kept by the United States secretary of state, and more generally for the impression it produces. The obverse of the Great Seal depicts the national coat of arms of the United States while the reverse features a truncated pyramid topped by an Eye of Providence. The year of the U.S. Declaration of Independence, 1776, is noted in Roman numerals at the base of the pyramid. The seal contains three Latin phrases: E Pluribus Unum, Annuit cœptis, and Novus ordo seclorum.
