The 1975 Austrian Grand Prix was a Formula One motor race held at Österreichring on 17 August 1975. It was race 12 in the 1975 Formula One season. It was held over 29 of the scheduled 54 laps for a race distance of 171 kilometres. The race was shortened by heavy rain, meaning that only half points were awarded. The weekend itself was marred by the deaths of Mark Donohue and a track marshal in a practice crash.

Mastering the wet weather, the race was won by Italian driver Vittorio Brambilla driving a March 751. It was Brambilla's only Formula One win in his seven-year Grand Prix career. He took a 27-second win over British driver James Hunt in his Hesketh 308. Eight seconds further back was the Shadow DN5 of British driver Tom Pryce in the first of just two podiums in his abbreviated career.
