Geoffrey Dearmer LVO (21 March 1893 – 18 August 1996) was a British poet. He was the son of Anglican liturgist and hymnologist Percy Dearmer and artist and writer Mabel Dearmer. During World War I, Dearmer was commissioned and served with the London Regiment at Gallipoli and on the Western Front. Many of his poems dealt with the overall brutality of war and violence, to which he was a direct eyewitness. His brother Christopher, a pilot with RNAS, died of wounds in 1915, and his mother Mabel died the same year while serving with an ambulance unit in Serbia.
