The 1991 Tooheys 1000 was the 32nd running of the Bathurst 1000 touring car race. It was held on 6 October 1991 at the Mount Panorama Circuit just outside Bathurst. The 1000 km race was held for cars complying with the provisions of Australian Group 3A Touring Car regulations with the field divided into three engine capacity divisions. It was the Round 2 of both the 1991 Australian Endurance Championship and the 1991 Australian Manufacturers' Championship.
Nissan driver Mark Skaife became the first driver since Peter Brock in 1983 to claim provisional pole position, pole position after the Top 10 runoff (with a then fastest touring car lap time of 2:12.63), the race win, as well as setting the races fastest lap, though his lap record in the race was set in the teams #2 GT-R and not the #1 he drove to victory with Jim Richards (Brock's race record lap of 1983 was also set in the team's second, #25 car, but that was the car he drove to victory with John Harvey and Larry Perkins).
The Richards / Skaife Nissan GT-R cruised to a one lap victory from the Holden Racing Team VN Commodore SS Group A SV of defending champions Win Percy and Allan Grice with the GIO Racing Nissan GT-R of Mark Gibbs and dual Australian Drivers' Champion Rohan Onslow a further lap behind in 3rd place. After having won the Sandown 500 in the lead up to Bathurst, 3rd place was enough to see Gibbs and Onslow win the Australian Endurance Championship and help win Nissan their 4th Australian Manufacturers' Championship.
The race was the first since 1986 that was run with no Safety car periods, with the overall race time of 6h 19m 14.80s breaking the 1984 record of 6h 23m 13.06s. The 1991 time remained as the race record for the 1000 km event until it was broken at the 2010 event with a 6h 12m 51.4153s race time. As of the end of 2015 the 1991 edition is still one of the fastest races in the history of this event, being the fifth fastest.

* 1991 was the first ever all-Nissan front row at Bathurst. It was also Nissan's third Bathurst pole position after George Fury claimed pole in 1984 in the Bluebird turbo, and Gary Scott had done so in 1986 in the Skyline DR30 RS turbo. With three GT-R's, Nissan also had its best ever representation in the runoff, breaking the record of two set in 1982 and 1986.
* 1991 was the only time between 1988 and 1992 that a Ford Sierra RS500 did not qualify on the pole. Glenn Seton in the fastest Sierra was over 2 seconds slower than Skaife and one second slower than the GT-R of second placed Mark Gibbs. His time was also 0.952 slower than Klaus Niedzwiedz's 1990 pole time in a Sierra.
* Peter Brock made his first appearance driving a Holden in the runoff since the first Group A race in 1985. Brock qualified his Holden VN Commodore SS Group A SV in 6th place. Compared to Skaife's speed on Conrod Straight in the twin-turbo GT-R, Brock's naturally aspirated V8 Commodore recorded 278 km/h (173 mph), though this was a substantial improvement as the older model Holden VL Commodore SS Group A SV usually topped out at around 270 km/h (168 mph) unless aided by a tow from another car. Despite this the VN Commodores were in fact almost 1.5 seconds slower than the VL model had been in 1990.
* 1991 was the only time between his pole positions in 1988 and 1992 that Dick Johnson did not qualify his #17 Sierra on the front row.
* Drew Price (Nissan), Larry Perkins (Commodore), David Parsons (Sierra), and Win Percy (Commodore) were the only drivers not to improve on their qualifying time. Price lost the most time, losing 2.336 seconds, though he still finished 7th.
* HRT team manager and defending race winner Win Percy, who was competing in his 6th Bathurst 1000, made his first appearance in the Top 10 runoff. In four of his previous five races his cars had in fact competed in the runoff but it was his co-drivers - Tom Walkinshaw in 1985 and Allan Grice in 1987, 1988 and 1990, who did the driving on those occasions (Percy did not drive in 1986 and only qualified 18th in 1989).
