Ōta-juku Nakasendō Museum (太田宿中山道会館, Ōta-juku Nakasendō Kaikan) is a museum dedicated to the history and culture of the Nakasendō's Ōta-juku and is located in the city of Minokamo, Gifu Prefecture, Japan.

The main focus of the exhibit is on the history and culture of Ōta-juku, one of the Nakasendō's shukuba. The displays include pieces related to Kazu-no-Miya Chikako who stayed at the shukuba while traveling the Nakasendō.

Part of the museum was built using materials from the house of Ippei Okamoto [ja], a famous artist who resided in the area from 1946 until his death two years later. This structure is separate from the main building and is a replica of Okamoto's completed house.
