The Caterham CT01 is a Formula One racing car produced by the British-based Caterham F1 Team which competed in the 2012 Formula One season. The car, designed under the leadership of the team's technical director Mike Gascoyne, chief designer Lewis Butler and head of aerodynamics Marianne Hinson, was the third car to be produced by the team and the first to carry the team's new name, following their renaming from Team Lotus at the end of 2011. The CT01 was the first car launched for the 2012 season, when an online launch initially planned for 26 January, was cancelled and the car was released a day earlier instead. The car was driven by Heikki Kovalainen and Vitaly Petrov, who replaced Jarno Trulli after the first test at Jerez.

The Caterham F1 Team was a Malaysian, later British owned Formula One team based in the United Kingdom which raced under a Malaysian licence. The Caterham brand competed in the Formula One World Championship from 2012 to 2014, following the acquisition of British sportscar manufacturer Caterham Cars by former owner and team principal Tony Fernandes, forming the Caterham Group.
