The 2023 Supercars Championship (known for commercial reasons as the 2023 Repco Supercars Championship) is a planned motor racing series for Supercars. It is due to be the twenty-fifth running of the Supercars Championship and the twenty-seventh series in which Supercars have contested the Australian Touring Car Championship, the premier title in Australian motorsport.
The 2023 season is expected to see the introduction of Gen3, a revision to the sport's technical regulations. These regulations were designed to cut costs for competitors by introducing more standardised components to the cars and redesigning the chassis to favour coupé body shapes.

Gen3 is expected to make its debut, replacing the Car of the Future regulations that débuted in 2013, with regulations designed to lower costs of a standard Supercar. It was due to début midway through 2022, but due to ongoing challenges with international supply chains and domestic disruptions caused by the COVID-19 pandemic, it was delayed to 2023.
The regulations are expected to introduce more controlled components into the cars to address the rising costs of maintaining a car. The pedal kit, brake kit and wheels will become control components, with tenders needing the rims to be 'finger friendly' for pit crew during a pit stop. The roll cage will be lowered by 100mm to be suited to coupes, after the controversy surrounding the Ford Mustang GT, which required the roof to be stretched beyond the dimensions of its road-going counterpart to fit. Supercars are planning to manufacturer the roll cage in kit form for teams that do not have the budget to build one themselves.
The engines on Gen3 are expected to be overhauled, with pushrod engines expected to be replaced with fuel-injected, DOHC V8 engines. This is intended to modernise the engine and significantly reduce costs of building and maintaining them.
Aerodynamic downforce will be cut by 67% to encourage closer racing and easier overtaking after complaints from drivers about dirty air and aerowash from current Gen2 cars.
Triple Eight Race Engineering will oversee the development of the Chevrolet Camaro ZL1 as a replacement for the Holden ZB Commodore. The Camaro ZL1 was chosen after parent company General Motors decided to discontinue the Holden brand and shut down production of the Commodore. Dick Johnson Racing will re-homologate the Ford Mustang to comply with the new regulations. They have planned to replace the existing V8 engine that was carried over from the Ford Falcon FG X with a Ford Coyote V8 engine.
