Hasegawa Settan (長谷川雪旦, 1778–1843) was a Japanese artist who lived during the late Edo period, born in Edo.
His given name was Munehide (宗秀), and his art-name was Gengakusai Ichiyōsai (巌岳斎 一陽庵). He was commonly called Gotō Uzaemon (後藤右衛門). He was originally a wood sculptor and he carved the woodblocks for many ukiyo-e prints. The Edo meisho zue, an illustrated catalogue of the sights of Edo for which he provided in the woodcuts, is one of his major works. <!--
He liked the haiku poem named Goraku (五楽): temporary blocked out while I investigate what this is about; as it stands, it has no significance for the English reader--> For his artistic accomplishments, Hasegawa Settan was awarded the honorary Buddhist title Hokkyō (法橋 "Bridge of the Dharma").
