The 2025 Supercars Championship (known for commercial reasons as the 2025 Repco Supercars Championship) was a motor racing series for Supercars. It was the 27th running of the Supercars Championship and the 29th series in which Supercars have contested the Australian Touring Car Championship, the premier title in Australian motorsport. It was the sixty-sixth season of touring car racing in Australia.

Will Brown and Triple Eight Race Engineering entered the championship as defending Drivers' and Teams' Champions respectively.

The 2025 season marked the first year in which the Finals Series was implemented, segmenting the season into three sections. Broc Feeney secured the inaugural Sprint Cup Championship at the first race of the Ipswich Super440. Matt Payne and Garth Tander won the 8th edition of the Enduro Cup following a win at Bathurst. Triple Eight clinched the Team's Championship for the record-breaking thirteenth season after the first race of the Sandown 500. Chaz Mostert won the Finals Series, in doing so securing his first ever Drivers' Championship.

Calendar changes The Bend Motorsport Park returned to the calendar, after missing out on the 2024 championship, as the first round of the Enduro Cup.

Queensland Raceway returned to the championship for the first time since 2019.

Sydney SuperNight moved from July to February, replacing the Bathurst 500.

Rule changes Format changes For 2025, the series was split into three categories, with each awarding its own title. The "Sprint Cup" was contested during first eight rounds. Two events—Sydney and Townsville—featured a 100 km Sprint Race on Friday and two 200km Feature Races on Saturday and Sunday with refuelling. One event—the Melbourne SuperSprint—featured four races of roughly 100 km. The remaining five will feature two 120km Sprint Races on Saturday and one 200 km Feature Race with refuelling on Sunday. The "Enduro Cup" returned for the first time since 2019, made up of The Bend 500 and the Bathurst 1000. The final three events contested a "Finals Series", similar to the NASCAR playoffs and Turismo Carretera Gold Cup.

Whilst the "Sprint Cup" and "Enduro Cup" will follow a traditional first-past-the-post championship system, the "Finals Series" will employ a combination of first-past-the-post and knockout elimination formats. 10 drivers took part in the first Finals Series round at the Gold Coast, held over two races of 250 km. These ten drivers consisted of the two Sprint and Enduro Cup Champions, with the remaining spots filled by the highest-placed drivers in the overall championship to that point. Drivers' points were reset to 3000, with bonus points awarded based on existing championship position (150-120-96-78-66-57-48-39-30-21). The Sprint and Enduro Cup Champions also received a bonus 25 points per title. The top 7 drivers with the most points following the Gold Coast round will then take part in the second Finals Series round at Sandown, held over two races of 250 km. Points are reset to 4000 with the same bonus points scale. The top 4 drivers will then take part in the last Finals round at Adelaide. This round is held over three races—one Sprint Race of 100 km on Friday, followed by two Feature Races of 250 km on Saturday and Sunday. Drivers' points reset to 5000 with bonus points now awarded on a sliding scale of 50-30-15-0. The driver with the most points after the three races in Adelaide will be crowned series' champion.

If a driver eligible for Finals points wins a race at the Gold Coast or Sandown, they automatically advance through to the next round. Drivers who do not qualify for the Finals in any form will continue to compete for points in the overall standings, as will drivers who are knocked out in the first two rounds of the Finals. Teams' Championship points are determined by their driver's regular season points.

Technical changes A new series of tyre compounds were introduced for the 2025 season. Instead of soft, medium and hard compounds, there were only two different dry-weather tyres, soft and super soft, with the former being revamped. Fuel towers were replaced with fuel churns for the Sprint Cup rounds. Additionally, co-drivers are now required to contest at least 37% of distance for Endurance races.
