Takeuchi Seihō (竹内 栖鳳, /takeɯᵝtɕiseːhoː/) (December 20, 1864 – August 23, 1942) was a Japanese painter of the Nihonga genre, active from the Meiji through the early Shōwa period.

One of the founders of nihonga, his works spanned half a century and he was regarded as master of the prewar Kyoto circle of painters.

His favorite subjects were animals -often in amusing poses, such as a monkey riding on a horse.

Many of his students later went on to establish themselves as noted artists, including Tokuoka Shinsen and Uemura Shōen.

[1] Later in his life he returned to more traditional Japanese motifs and painted smaller animals such as cats and fish.
