The Toyota TF108 was a Formula One car designed and engineered by Toyota to compete in the 2008 Formula One season. The chassis was designed by Pascal Vasselon, John Litjens and Mark Gillan with the engine being designed by Luca Marmorini and Noritoshi Arai overseeing the entire project. The car's best finish was second in the Hungarian Grand Prix, driven by Timo Glock.

The 2008 Toyota challenger, the Toyota TF108, was launched on 10 January 2008, at the team's factory in Cologne, Germany.

Jarno Trulli was retained as one of the team's drivers for the 2008 season and was joined by former Jordan driver Timo Glock. The Toyota test and reserve driver for the 2008 season was Japanese driver Kamui Kobayashi.

The Toyota team let driver Ralf Schumacher go at the end of the 2007 Formula One season, Schumacher then signed a contract with Mercedes-Benz in the DTM for the 2008 season.

The TF108 had a new longer wheelbase to aid stability and a totally new aero package that was hoped to give the car great potential. It was not an evolution of the previous year's TF107; instead it had been designed from an evolution of the TF106, used for the 2006 season. Pascal Vasselon, the team's chassis general manager noted that the "primary aerodynamic design philosophy for the TF108 is geared towards optimising the entire package".

The car also had the new for 2008 higher headrests around the drivers head and also had the new standard McLaren Electronic Systems ECU that prevented the car having driver aids.

Toyota had adopted a McLaren MP4-22-like bridge on the front wing, and also moved the rear view mirrors outboard, like Ferrari and Renault. The TF108 had also had a major focus on cleaning the air flow around the front suspension, maximising the zero keel concept of the front suspension.

At the French Grand Prix, the car ran a black stripe along the nosecone to commemorate the life of former boss, Ove Andersson, who had died earlier that month.
