Sir Douglas William Falconer, MBE (20 September 1914 – 18 December 2007) was an English barrister and High Court judge.
On the outbreak of the Second World War, Falconer was commissioned in the East Yorkshire Regiment, fought with the British Expeditionary Force, and was among the last to be evacuated at Dunkirk.
He played an important role in training and planning for D-Day, for which he was appointed a MBE (Military Division).
He completed his pupillage with Guy Aldous (the father of William Aldous, later Falconer's own pupil and a Lord Justice of Appeal) in the chambers of Kew Shelley at 6 Pump Court Chambers, where he remained for the remainder of his career at the bar.
In 1981, Falconer was appointed to the High Court of Justice, receiving the customary knighthood.
