Beauregard is an unincorporated community located in central Lee County, Alabama, United States. It is located east of Auburn and south of Opelika.

Beauregard was settled in the late 19th century and was named for Confederate General P.G.T. Beauregard. There are also some unidentified ruins along Road 166 that sit behind the limestone quarry.

On March 3, 2019, Beauregard was hit by a long-tracked EF4 tornado. Many homes and businesses were severely damaged or destroyed, and 23 people were killed.

While Beauregard has been traditionally considered to be a small area near the crossroads of Alabama State Route 51 and Lee County Road 400, today most residents within a roughly 25 square mile (65 km) area surrounding the original community consider themselves to be in "Beauregard".

Via AL-51, Opelika, the Lee County seat, is 8 mi (13 km) north, and Marvyn is 8 mi (13 km) south.

Beauregard is part of the Auburn Metropolitan Area.
