Sanuki Province (讃岐国 Sanuki-no kuni) was an old province of Japan in the area of Kagawa Prefecture on the island of Shikoku. It was sometimes called Sanshū (讃州).
The province had borders with Awa and Iyo Provinces.
In the Meiji period, the provinces of Japan were converted into prefectures. The maps of Japan and Sanuki Province were reformed in the 1870s.
Sanuki faced the Seto Inland Sea.
