Flat Rock is a village in Henderson County, North Carolina, United States. The population was 3,114 at the 2010 census. It is part of the Asheville Metropolitan Statistical Area.

Charles Baring and Susan Heyward Baring built Mountain Lodge in 1827 as the community became known as the "Little Charleston of the Mountains" due to an influx of wealthy summer residents from the South Carolina Low Country. Historic Flat Rock Inc. bought the abandoned house and sold it in 2014 to Julien Smythe, a descendant of an owner of Connemara who along with wife Lori renovated the house.

A post office called Flat Rock has been in operation since 1829. The village was named for granite rock formations which dotted the landscape.
