The Poet Laureate Consultant in Poetry to the Library of Congress, commonly referred to as the United States Poet Laureate, serves as the official poet of the United States. During their term, the poet laureate seeks to raise the national consciousness to a greater appreciation of the reading and writing of poetry. The position was modeled on the Poet Laureate of the United Kingdom. Begun in 1937, and formerly known as the Consultant in Poetry to the Library of Congress, the present title was devised and authorized by an Act of Congress in 1985. Appointed by the Librarian of Congress, the poet laureate's office is administered by the Center for the Book. For children's poets, the Poetry Foundation awards the Young People's Poet Laureate.

A poet laureate is a poet officially appointed by a government or conferring institution, typically expected to compose poems for special events and occasions. Albertino Mussato of Padua and Francesco Petrarca (Petrarch) of Arezzo were the first to be crowned poets laureate after the classical age, respectively in 1315 and 1342. In Britain, the term dates from the appointment of Bernard André by Henry VII of England. The royal office of Poet Laureate in England dates from the appointment of John Dryden in 1668.
