RAAF Base Tindal is a Royal Australian Air Force (RAAF) military air base and civil aviation airfield located 8 nautical miles east southeast of the town of Katherine, Northern Territory in Australia. The base is currently home to No. 75 Squadron and a number of non-flying units, and also hosts the civilian Katherine Tindal Airport. First constructed in 1942, it was refurbished in the late 1960s as a bare base capable of being utilised when required. It was opened as a permanently manned RAAF base in 1989.
