Tohwasà  (), translated as Korean Royal Academy of Painting, was an administrative office of the Joseon period responsible for drawing pictures requested by other government offices. It was originally called Tohwawà Ân () during the Goryeo period until it was later renamed under Yejong, but its class was dropped, and the office was later renamed to Tohwasà Â.
According to the Kyà Ângguk taejà Ân, or National Code, the organizational structure of the Tohwasà  comprised one Jeju (), two Byeolje (), and twenty miscellaneous workers. The organization's main task was to paint artworks for the nation, such as Uigwe. In addition, its artists drew portraits of the king, popular men and maps.
Artists who worked within the Tohwasà  were called Hwawon or Hwasa. An Kyà Ân, who was a hwawon during the reign of Sejong the Great, is renowned for his Shan shui, and for the works Mongyudowondo and Sasipaljungdo. Kim Hongdo and Sin Yunbok were also renowned Hwawon for their drawings.
