Keisai Eisen (渓斎 英泉, 1790 – 1848) was a Japanese ukiyo-e artist who specialised in bijinga (pictures of beautiful women). His best works, including his ōkubi-e ("large head pictures"), are considered to be masterpieces of the "decadent" Bunsei Era (1818–1830). He was also known as Ikeda Eisen, and wrote under the name of Ippitsuan.
