Lock Wood Island is an island in the River Thames in England just downstream of Nuneham House on the reach above Abingdon Lock.
The island sits on a sharp bend in the river.
It is densely covered with tall trees and has a narrow channel behind it.
In the nineteenth century there was a thatched cottage on the island linked to the bank by a rustic bridge which was a popular place for picknickers.
There is evidence of weirs and flash locks here, at one time owned by Lord Harcourt, which may account for the name of the island.
