This is a list of the oldest-known trees, as reported in reliable sources. Definitions of what constitutes an individual tree vary. In addition, tree ages are derived from a variety of sources, including documented "tree-ring" (dendrochronological) count core samples, and from estimates. For these reasons, this article presents three lists of "oldest trees," each using varying criteria.
There are three tables of trees, which are listed by age and species.
