The Arbutus Oak was a large white oak tree in Arbutus, Maryland, situated in the southwest corner of the I-695/I-95 interchange approximately four miles southwest of Baltimore. It split and half and fell in 2019, due to internal decay that caused its trunk to become unstable. At that time, it was thought to be 329 years old.
