Sin Yunbok, better known by his art name Hyewŏn, was a Korean painter of the Joseon period. Like his contemporaries Kim Hongdo and Kim Tŭksin, he is known for his realistic depictions of daily life in his time. His genre paintings are distinctly more erotic than Kim Hongdo's, a fact which contributed to his expulsion from the royal painting institute, Tohwasŏ.
