Sacheon is a city in South Gyeongsang Province, South Korea. Sacheon's chief fame comes from its being the site of two naval battles in the Seven Year War.

The city as it now exists results from the merging of Sacheon-gun and Samcheonpo-si in 1995. The northern part of the city is called Sacheon-eub and is located at the top of Sacheon Bay, near the city of Jinju. The southern part of the city is located in the old Samcheonpo-si, which is located at the mouth of Sacheon Bay.
