95th Siege Battery was a heavy howitzer unit of Britain's Royal Garrison Artillery (RGA) raised during World War I. It manned heavy howitzers on the Western Front from 1916 to 1918, beginning with the Attack on the Gommecourt Salient on the First day on the Somme. It then served at Vimy Ridge and Ypres, against the German Spring Offensive and in the final Allied Hundred Days Offensive.
