The Australian Operational Service Medal is a campaign medal established on 22 May 2012 to recognise service by Australian Defence Force (ADF) personnel on designated hazardous operations.

The medal is issued to military personnel with a different ribbon for each designated operation. When issued to civilians, a standard ribbon is issued with clasps issued for each designated operation.
