State Route 147 is a public highway maintained by the state of Alabama in east central Alabama. The highway acts as a connector between U.S. Highway 29 and Interstate 85 in the southern part of Auburn, Alabama, U.S. Highway 280 in northern Auburn, and U.S. Highway 431 between Auburn and Lafayette, Alabama.

State Route 267 is a bypass of SR-147.

SR-147 lies mostly within the city limits of Auburn, Alabama. Approximately one mile of the road runs through unincorporated Lee County, while 4.2 miles (6.8 km) lies in rural Chambers County.

Alabama State Route SR-147 begins on College Street in Auburn and continues for 8.6 miles until it shares one block with Alabama State Route 14 (SR-14) in downtown Auburn. It continues along Birmingham Highway and U.S. Route 280 (US-280) along with (State Route 38) (SR-38) to mile 9.0, then continues on Heath Road in northern Auburn.

In 1939, the state of Alabama constructed the original segment of SR-147, connecting U.S. Highway 29 in downtown Auburn to what was then U.S. Highway 241 (now US-280) at The Bottle. In 1947, SR-147 was extended north three miles (5 km) to Gold Hill. The final extension from Gold Hill to U.S. Highway 431 to complete the northern portion of the highway did not occur until 1960. In 1998, the relocation of U.S. Highway 29 to the Interstate 85 freeway led to the movement of the southern terminus of the highway from the intersection of Mitchum Avenue and College Street in downtown Auburn to a point four miles (6 km) south at the College Street interchange with Interstate 85.

In 2006, the Alabama Department of Transportation began a relocation study for the southern half of SR-147. The study is to look at the possibility of rerouting the highway some four miles (6 km) west of Auburn, along the route of the proposed Auburn Outer Loop. The proposed relocation would begin at Interstate 85 at the under-development Cox Road interchange (Exit 50) and would travel north thirteen miles (19 km) to connect with US-280 at mile marker 101.4, where it would join the current northern section of SR-147.
