The 1985 James Hardie 1000 was a motor race held on 6 October 1985 at the Mount Panorama Circuit just outside Bathurst, in New South Wales, Australia. It was the 26th running of the Bathurst 1000 and was the first held exclusively for cars complying with the Australian version of International Group A touring car regulations. The event, which was organised by the Australian Racing Drivers Club Ltd, was Round Four of both the 1985 Australian Endurance Championship and the 1985 Australian Manufacturers' Championship.
The race was dominated by the Tom Walkinshaw Racing run Jaguar XJ-S's, which finished first and third. John Goss and German driver Armin Hahne claimed the victory with team owner Tom Walkinshaw and his co-driver Win Percy finishing three laps down in third. On the same lap as the winning Jaguar was the Schnitzer Motorsport prepared BMW 635CSi of Italian driver Roberto Ravaglia and Venezuela's former Motorcycle World champion (and ex-Formula One driver) Johnny Cecotto who, despite their extensive overseas experience, were Bathurst rookies and as such easily co-won the Rookie of the Year award. The Holden Dealer Team Holden VK Commodore of Peter Brock and New Zealand open-wheel racer David Oxton was in second place with three laps to go when it broke a timing chain and retired.
1985 was the first Great Race since 1968 in which four-time winner Allan Moffat was not an entrant. Left without a drive in 1985 after the withdrawal of Mazda from Australian touring car racing, Moffat was guest expert commentator with race broadcaster Channel 7.
The 1985 James Hardie 1000 was also the first Great Race since 1966, to be won by a car manufacturer other than Ford or Holden.
