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.

During the Exposition Universelle in Paris (1900), he toured Europe, where he studied Western art.

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.
