The Buttonball Tree is an exceptionally large American sycamore (Platanus occidentalis) located in Sunderland, Massachusetts.

Because of their longevity, during the 17th and 18th century sycamores were sometimes planted at the door of new houses for newlyweds as "bride and groom" trees.

Though the age of the tree is unknown, it is estimated to be well over 350 years old, with many estimates saying that the tree is closer to 400.
