The Shiawassee River (/ˌʃəˈwɒsi/ SHY-ə-WOSS-ee) in the U.S. state of Michigan drains an area of 1,201 square miles (3,110 km2) within Oakland, Genesee, Livingston, Shiawassee, Midland and Saginaw counties. It flows in a generally northerly direction for approximately 110 miles (180 km) from its source to its confluence with the Tittabawassee River creating the Saginaw River, which drains into Saginaw Bay of Lake Huron.

The name is derived from the Chippewa "shia-was-see" meaning "the river straight ahead."
