Angel Oak is a Southern live oak located in Angel Oak Park on Johns Island near Charleston, South Carolina. Angel Oak is 400 years old. It stands 66.5 ft (20 m) tall, measures 28 ft (8.5 m) in circumference, and produces shade that covers 17,200 square feet (1,600 m²). Its longest branch distance is 187 ft in length. Angel Oak was the 210th tree to be registered with the Live Oak Society.
The tree stands on land that was part of Abraham Waight's 1717 land grant.
The oak derives its name from the estate of Justus Angel and his wife, Martha Waight Tucker Angel. Local folklore tells stories of ghosts of former slaves appearing as angels around the tree.
Despite the popular belief that Angel Oak is the oldest tree east of the Mississippi River, many bald cypress trees are found throughout the South which are many hundreds of years older.
The Angel Oak tree is featured prominently in the book The Heart of A Child by Emily Nelson.
