The Civil Service Rifles War Memorial is a First World War memorial located on the riverside terrace at Somerset House in central London, England. Designed by Sir Edwin Lutyens and unveiled in 1924, the memorial commemorates the 1,240 members of the Prince of Wales' Own Civil Service Rifles regiment who were killed in the First World War. They were Territorial Force reservists, drawn largely from the British Civil Service, which at that time had many staff based at Somerset House.
