Winkworth Arboretum is a National Trust-owned arboretum in the spread-out civil parish of Busbridge between Godalming and Hascombe, south-west Surrey, England. Winkworth Arboretum exhibits large collections of azalea, rhododendron, and holly on slopes leading down to landscaped garden lakes. Gertrude Jekyll explored the woods in the early 20th century. The exotic trees were planted from 1938 by Wilfrid Fox.
