Baron Phillimore, of Shiplake in the County of Oxford, is a title in the Peerage of the United Kingdom. It was created in 1918 for the former Judge of the High Court of Justice and Lord Justice of Appeal, Sir Walter Phillimore, 2nd Baronet. The Phillimore Baronetcy, of The Coppice, had been created in the Baronetage of the United Kingdom on 28 December 1881 for his father Sir Robert Phillimore, who was also a noted lawyer and judge. The first Baron was succeeded by his son, the second Baron.
On his death the titles passed to his grandson, the third Baron, his eldest son Captain the Hon. Anthony Francis Phillimore (d. 1940) having been killed in action during the Second World War. The third Baron was childless and was succeeded by his uncle, the fourth Baron. He was an architect.
The Phillimore family were formerly owners, and now trustees, of the Phillimore estate  in Kensington, west London, covering the prosperous 19th century houses around Holland Park and Campden Hill.
