The Libelle of Englyshe Polycye (or "Libel of English Policy") is a fifteenth-century poem written in English. The work exists in two redactions: the first was composed after the siege of Calais in 1436 but before the end of 1438, and a second edition of the work before June 1441. This second edition was probably revised again. Nineteen manuscripts contain the "Libelle", which consists of about 1,100 lines in rhyming couplets, with a proem in rhyme-royal and a stanzaic envoi that differs between the poem's two editions.
