The Australian Defence Force Investigative Service (ADFIS) is the unified investigative arm of the Australian Defence Force's Joint Military Police Unit. Initially formed in 2007 as a part of the service police until its amalgamation into the Joint Military Police Force at the beginning of 2020. ADFIS was responsible for complex and major disciplinary and criminal investigations involving the Australian Defence Force (ADF), its assets, land, personnel and capability.

ADFIS is a tri-service unit that was composed of specialised service police personnel who are qualified to undertake investigations of serious and unique nature. As the successor to the previously active single-service police investigation units which it absorbed, it is staffed by military police officers from the Royal Australian Navy's Naval Police, Australian Army's Military Police and the Royal Australian Air Force's Air Force Police.
