Captain Andrew Gillison (7 June 1868 – 22 August 1915) was an Australian minister who served as a Presbyterian chaplain in the Australian Army. He was born and educated in Scotland and practised there as a minister. Gillison also served in the Volunteer Force's Queen's Edinburgh Rifles. He emigrated to Australia in 1903 to take up a post at St Paul's Presbyterian Church, Spring Hill, and, from 1909, at St George's Church in St Kilda East, Victoria.
Gillison was appointed a chaplain to the Australian military in 1906. After the outbreak of the First World War he was appointed a chaplain-captain to the 14th Battalion. He was posted with them to the Dardanelles campaign and landed at Anzac Cove within the first few days of the operation. During the campaign Gillison assisted with wounded soldiers, buried the dead and carried out religious services. Despite his non-combatant status he took up arms to snipe at Turkish soldiers. Gillison was killed on the second day of the Battle of Hill 60 while trying to retrieve a wounded soldier from no man's land.
