The Ashbrittle Yew is an ancient yew tree located in the village of Ashbrittle, Somerset, in southwest England. The yew grows on a tumulus in the south-east end of the churchyard of St. John the Baptist. Yews are capable of living for several thousands of years; the Ashbrittle Yew itself is believed to be over 3,000 years old, but defining its precise age is difficult due to its hollow centre. The tree is formed of a hollow central trunk surrounded by six narrower boles. In 2015 its measured diameter was 39 ft 11 in (12.17 m).
