Gracie Abbott, 13, was airlifted to Children’s of Alabama in Birmingham after the accident, which happened near Old Glory Drive, just off Fall City Road.
Abbott was driving the ATV but lost control and the vehicle flipped, throwing Abbott and two of her cousins from the vehicle, officials said.
Abbott was airlifted to the hospital with a severe head injury, but efforts to revive her failed.
Abbott was pronounced dead at 10:15 p.m., Walker County Coroner J.C. Poe said.
