The Loos Memorial is a World War I memorial forming the sides and rear of Dud Corner Cemetery, located near the commune of Loos-en-Gohelle, in the Pas-de-Calais département of France. The memorial lists 20,610 names of British and Commonwealth soldiers with no known grave who were killed in the area during and after the Battle of Loos, which started on 25 September 1915. This memorial covers the same sector of the front as the Le Touret Memorial, with each memorial commemorating the dead either side of the date of the start of the Battle of Loos.
Designed by Sir Herbert Baker, the sculptures were by Sir Charles Wheeler. The memorial was unveiled on 4 August 1930 by Sir Nevil Macready. General Macready served as Adjutant-General of the British Expeditionary Force from the outbreak of the war to February 1916, and then served as Adjutant-General to the Forces until a few months before the end of the war.
