Kamada Foundation Museum, Local history museum in Sakaide, Japan.

The Kamada Foundation Museum occupies a three-storey reinforced-concrete building completed in 1922 as the Kamada Kyosaikai Library, with 446.31 m² of floor area on the ground and 634.58 m² in total. Its displays draw on more than 10,000 objects on Kagawa Prefecture, from early modern and modern calligraphy and painting to photographs, archaeological material and mineral specimens. The building was registered as a Tangible Cultural Property in 1998.

The Kamada Foundation was established in 1918 by Katsutaro Kamada, a businessman and member of the House of Peers, for charity, education and social education. Its museum opened on 24 May 1925, with local historian Tadakichi Okada as first curator. In 1992 the original building was demolished for the JR Yosan Line elevation project, and the museum moved into the 1922 Kamada Foundation Library building, used as Sakaide City Library from 1951 to 1979. That building was registered as a Tangible Cultural Property on 11 December 1998.

The museum's core is the Kume Tsūken collection: 1,061 items designated a National Important Cultural Property in 2014, split into 595 documents and records, 295 letters, 115 maps and drawings, 11 manuscript drafts, 20 classical texts and 25 artefacts. Kume was a Western-learning scholar and inventor in the late Edo-period Takamatsu domain. The first head of the museum was local historian Okada Tadayoshi.

The museum is a five-minute walk from JR Sakaide Station on the Yosan Line. It opens from 9:30 to 16:30, with last entry at 16:00, and closes on Mondays, public holidays, 13–15 August and 29 December–4 January. Admission is free, and the Kofuen garden and Kamada Soy Sauce head office stand next door.

The museum occupies a 1922 reinforced-concrete building of three floors, built as the Kamada Kyosaikai Library and used as Sakaide City Library from 1951 to 1979. It was registered as a Tangible Cultural Property in 1998 under the name "Kamada Kyosaikai Local Museum (Former Library)".
