Oldberrow is a village in the Stratford-on-Avon District of Warwickshire, England. The parish was part of Worcestershire until 1896, when it was transferred to Warwickshire, into which county it penetrated, between Morton Bagot and Ullenhall, as a narrow strip some 3 miles (4.8 km) long by about ½ mile wide. It is now part of the parish of Morton Bagot, Oldberrow and Spernall which in the 2001 Census had a population of 153. The land slopes from 513 ft (156 m) at Oldberrow Hill in the north-west to about 275 ft (84 m) in the south-east. There is no village, but the church, rectory, and the Court lie at the crossing of four small roads.
