Ha Jaeyoun (the romanization preferred by the author according to LTI Korea[1]) (Hangul 하재연; born 1975) is a South Korean poet and professor.

She made her literary debut in 2002 when the journal Literature and Society published several of her poems, including "Isibosi supeomaket" (25시 슈퍼마켓 The Supermarket at the 25th Hour).

Since then she has published two poetry collections entitled Radio deijeu (라디오 데이즈 Radio Days) (2006) and Segyeui modeun haebyeoncheoreom (세계의 모든 해변처럼 Like All Beaches in the World) (2012), as well as a monograph called Geundaesiui moheomgwa umjigineun joseoneo (근대시의 모험과 움직이는 조선어 The Adventure of Modern Poetry and the Changing Korean Language) (2012).

Ha Jaeyoun's poetry reflects on familiar objects found in reality but manages to convey a new sensibility.

Ha describes how people have grown accustomed to meaningless relationships and futile emotions in a society of dazzling spectacle.

[4] Ha's first poetry collection Radio deijeu (라디오 데이즈 Radio Days) often uses everyday objects and experiences as subject matter, such as a cloud, bench, park, sunlight-filled window, TV screen, comic book shop around the corner, sleepy afternoon, and shabby neighborhood house with an iron gate.

But when Ha describes her subjects, she also expresses doubt about her memory of them; the objects and phenomena portrayed in her work are constantly moving and changing.

[5] Her second poetry collection Segyeui modeun haebyeoncheoreom (세계의 모든 해변처럼 Like All Beaches in the World) allows readers to visualize abstract spaces using images of dolls, ghosts, animals, and more.
