Lithia Springs (/ˈlɪθiːə/) is an unincorporated community and census-designated place, formerly incorporated as a city, located in northeastern Douglas County, Georgia, United States.

Lithia Springs became incorporated again in 1994, to be Douglas County's second completely internal municipality, but disincorporated again in 2000.

So popular were the curative waters that flowed from Lithia Springs that people came for miles to drink it.

That same year the Sweet Water Hotel, a 300-room luxury health resort, opened in Lithia Springs.

[4] The hotel and its famous lithia spring water were so popular that Mark Twain, members of the Vanderbilt family, and Presidents Cleveland, Taft, McKinley and Theodore Roosevelt all enjoyed the many amenities of the resort, which included the world-famous Lithia Vapor Baths.

Henry W. Grady, editor of the Atlanta Constitution, was the founder and gave the institute the motto "Enlightenment of the People".

The park is home to the George Sparks Reservoir, owned and maintained by the City of East Point.

In 2005, the remnants of Hurricane Dennis damaged the bridge over the reservoir, the main road into and out of the park.
