Walkinshaw Andretti United is an Australian motor racing team based in the Melbourne suburb of Clayton. The team currently fields two Holden ZB Commodores in the Supercars Championship for James Courtney and Scott Pye, along with a Porsche 911 GT3-R in the Australian GT Championship.
Formed in 1990 as the Holden Racing Team, it is one of the most successful Supercars Championship teams in the history of the category, having won the drivers' championship six times, and the series' signature race, the Bathurst 1000, seven times. In 2017, the Holden Racing Team name was transferred by Holden to Triple Eight Race Engineering and the team was renamed Mobil 1 HSV Racing. For the 2018 season, the team was rebranded Walkinshaw Andretti United, as Andretti Autosport and United Autosports become shareholders.
