Hunminjeongeum Haerye (Korean: 훈민정음 해례; Hanja: 訓民正音解例), or simply Haerye, refers to either a commentary section on the text Hunminjeongeum or to copies of the Hunminjeongeum that contain the commentary section. The Hunminjeongeum and commentary were published together as a single text around October 1446 (Gregorian calendar). Together, they introduce the native Korean alphabet Hangul.
The Joseon king Sejong the Great (r. 1418–1450) authored the preface to the overall text as well as the basic introduction of the letters. The following members of the government agency Hall of Worthies coauthored the Haerye section: Chŏng Inji, Ch'oe Hang, Pak P'aengnyŏn, Sin Sukchu, Sŏng Sammun, Kang Hŭian, Yi Kae, and Yi Sŏllo. The text's postface was written by Chŏng Inji. The commentary and postface describe how the shapes of Hangul's letters were derived.
