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.
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 km2) area surrounding the original community consider themselves to be in "Beauregard".[citation needed]
