The Treaty Oak is a southern live oak estimated to be between 200 and 250 years old, standing in Jessie Ball duPont Park near the south bank of the St. Johns. Its canopy spreads over an area of roughly a quarter of an acre, supported by massive horizontal limbs that reach close to the ground before curving upward. It is one of the largest trees in Florida and one of the most beautiful.
The name comes from a folk tradition that the tree marked a meeting place between European settlers and local Indigenous people, though no historical evidence supports this. The tree predates European settlement of the area and has outlasted everything that Jacksonville has built around it. It is free to visit and open during park hours.
