Dinjan Airfield, also known as Dinjan Air Force Station, is an air base of Indian Air Force. Established as an air field in World War II, it is located in Dinjan, approximately seven miles northeast of Chabua, in the state of Assam, India.

The fall of Singapore and Rangoon in early 1942 propelled Dinjan airbase to be the centre of attention as the main supply line between India and China. It housed a major hospital for evacuees from Burma during the Second World War. It was abandoned after the war, till 1964 when Indian Air Force established its surveillance base here. It houses one squadron of Apache attack helicopters.
