Yun Du-seo (1668–1715) was a painter and scholar of the Joseon period. He is the grandson of Yun Seondo, a great scholar in Korean history. He passed the gwageo exam, but did not enter government service. Rather, he devoted his whole life to painting and studying Confucianism. His self-portrait is regarded as one of the many masterpieces of Korean art. Yun Duseo is also known for his yeongmohwa (animal-and-bird painting).
