Shimosuwa-shuku (下諏訪宿 Shimosuwa-shuku) was the twenty-ninth of the sixty-nine stations of the Nakasendō, as well as being the ending location of the Kōshū Kaidō. It is located in the present-day town of Shimosuwa, Suwa District, Nagano Prefecture, Japan.
First built around 1601, Shimosawa-shuku flourished as a post town because it was located between two difficult mountain passes, Wada Pass and Shiojiri Pass. The town's onsens made it a heavily used rest area. It also served as the entrance to the Suwa Taisha.
