Alexander City, known to locals as "Alex City", is a city in Tallapoosa County, Alabama, United States, with a population of some 14,875. The city was traditionally based around the textile industry, but in recent times its economic base has become more diversified as textile jobs have gone elsewhere.

Alexander City was incorporated in 1872 as Youngsville, after its founder James Young. In 1873 the Savannah and Memphis Railroad came to the city. The city was renamed in honor of the railroad's President Edward Porter Alexander, hero of the Battle of Gettysburg for the Confederate States.

On June 13, 1902, at 1 pm, a fire broke out in the Alexander City Machine shop and destroyed much of the town. At the time, Alexander City did not have a water system and all buildings, including the telegraph office, post office and three banks were burned.
