The 1st Pioneer Battalion was an Australian infantry and light engineer unit raised for service during the First World War as part of the all volunteer Australian Imperial Force (AIF). Formed in Egypt in March 1916, the battalion subsequently served on the Western Front in France and Belgium. Assigned to the 1st Division, the 1st Pioneer Battalion fought in most of the major battles that the AIF participated in between mid-1916 and the end of the war in November 1918. It was subsequently disbanded in early 1919.
