The Ken Domon Museum of Photography (土門拳記念館, Domon Ken kinenkan) was opened in 1983 in Sakata, Yamagata (Japan), the birthplace of the photographer Ken Domon.

On the occasion of becoming the first honorary citizen of Sakata in 1974, Domon donated his entire collection of works to the town.

The museum has about 70,000 prints of works by Domon.

The museum building was designed by noted architect Yoshio Taniguchi, and won the 9th Isoya Yoshida Award in 1984.
