Santō Kyōden (山東 京伝?, September 13, 1761 Edo – October 27, 1816) was a Japanese poet, writer and artist in the Edo period. His real name was Iwase Samuru (岩瀬 醒?), and he was also known popularly as Kyōya Denzō (京屋伝蔵 kyōya denzō?). He is the brother of Santō Kyōzan.
Santō Kyōden was born in Fukagawa in Edo. The Iwase family into which he was born were pawnbrokers in a lumberyard. He studied ukiyo-e under master Kitao Shigemasa (北尾 重政?), and began illustrating kibyōshi under the pseudonym of Kitao Masanobu (北尾 政寅?). He soon started writing these novels also under the name of Santō Kyōden; several novels are labeled as written by Santō Kyōden and illustrated by Kitao Masanobu. He wrote kibyōshi and sharebon in great numbers, and became a popular writer. During this time he married twice, both his wives being licensed workers of Yoshiwara.
