David John Garland (1864–1939) was an Anglican clergyman and a military chaplain in Queensland, Australia. As senior army camp chaplain in Queensland from 1914 to 1917, Garland experienced the World War I both at home and at the front. He was one of the originators of the now annual Anzac Day ceremonies. Described as "overpoweringly energetic with a distinctive flair, if not genius, for organisation", he played a pivotal role in the Queensland experience of the war, and was a central figure in a variety of committees and organisations established to aid the war effort and support or commemorate serving or returned soldiers.
