Henry V is a history play by William Shakespeare, believed to have been written near 1599. It tells the story of King Henry V of England, focusing on events immediately before and after the Battle of Agincourt (1415) during the Hundred Years' War. In the First Quarto text, it was titled The Cronicle History of Henry the fift, and The Life of Henry the Fifth in the First Folio text.

In the First Folio, the plays of William Shakespeare were grouped into three categories: comedies, histories, and tragedies. The histories—along with those of contemporary Renaissance playwrights—help define the genre of history plays. The Shakespearean histories are biographies of English kings of the previous four centuries and include the standalones King John, Edward III and Henry VIII as well as a continuous sequence of eight plays. These last are considered to have been composed in two cycles. The so-called first tetralogy, apparently written in the early 1590s, covers the Wars of the Roses saga and includes Henry VI, Parts I, II & III and Richard III. The second tetralogy, finished in 1599 and including Richard II, Henry IV, Parts I & II and Henry V, is frequently called the Henriad after its protagonist Prince Hal, the future Henry V.
