Interstate 75 (I-75) in the US state of Georgia travels north–south along the U.S. Route 41 (US 41) corridor in the central part of the state, traveling through the cities of Valdosta, Macon, and Atlanta. It is also designated—but not signed—as State Route 401 (SR 401).

I-75 is the only Interstate to traverse the full length of the state from north to south, from the flat Atlantic Coastal Plains in southeast Georgia to the rolling mountains of North Georgia. In Downtown Atlanta, I-75 runs concurrently with I-85 as the Downtown Connector. The segment from SR 49 in Byron to I-16 in Macon is part of the Fall Line Freeway and may be incorporated into the eastern extension of I-14, which is currently entirely within Central Texas and is proposed to be extended to Augusta.

What would become the general routing of I-75 in Georgia was initially used by the western routing of the Dixie Highway beginning in 1916. Established in 1926, the Interstate's direct predecessor in Georgia is US 41, a national highway that has been largely supplanted in favor of the federally-funded freeway built under the Interstate Highway System—though limited-access elements of the Interstate existed as early as 1951.
