62nd Siege Battery was a heavy howitzer unit of Britain's Royal Garrison Artillery (RGA) formed in Kent during World War I. It saw active service on the Western Front at the Somme and on the Ancre, at Bullecourt, Messines and Passchendaele. The battery was overrun and lost its guns during the German Spring Offensive, but was re-equipped and took part in the final Allied Hundred Days Offensive.
