Chestnutflat is an unincorporated rural hamlet in Walker County, in the U.S. state of Georgia. There is only a used-car business at Chestnutflat, and several homes.
A variant name is "Chestnut Flat". A post office called Chestnut Flat was established in 1841, and remained in operation until 1904.[1] The community was named for a grove of chestnut trees near the original town site.[2]
