Shiba Kōkan, born Andō Kichirō or Katsusaburō, was a Japanese painter and printmaker of the Edo period, famous both for his Western-style yōga paintings, in imitation of Dutch oil painting styles, methods, and themes, which he painted as Kōkan, and his ukiyo-e prints, which he created under the name Harushige, but also producing forgeries of the works of Suzuki Harunobu. He is said to have boasted of his ability to forge the great master so well. He also was engaged in Western learning in the field of astronomy.
