Matthieu Lahaye (born 23 November 1984 in Rennes) is a French racing driver. He competed in the FIA World Endurance Championship for OAK Racing in 2012 and for Ultimate in 2022. Along with his brother Jean-Baptiste, he runs a small sports car racing team called Ultimate.
2008 saw Lahaye switch to sportscars, driving in the Le Mans Series for Saulnier Racing. Racing a Pescarolo Sport-Judd with Pierre Ragues, he finished fifth in the LMP2 standings. He also took part in his first 24 Hours of Le Mans with the team together with Ragues and China's Congfu Cheng, finishing 18th overall and third in LMP2.
In 2009, Lahaye continued with the team (now renamed OAK Racing) in the LMP2 class of the LMS, with Karim Ajlani as his teammate. They scored two podium finishes from the five races, finishing ninth in the final standings. He and Ajlani were joined at Le Mans by Guillaume Moreau, but the car retired from the race. Lahaye did win the class in the two races at Okayama that made up the 2009 Asian Le Mans Series, partnering team owner Jacques Nicolet and Richard Hein.
In 2010, Lahaye partnered Nicolet in the Le Mans Series, and finished the year third in LMP2. At Le Mans, he finished seventh overall and second in LMP2, sharing with Moreau and Jan Charouz.
In 2011, Lahayt contested the LMP1 category of the Intercontinental Le Mans Cup with OAK. However, a heavy accident in qualifying at Spa left him with two broken vertebrae, a broken hand and an injured knee, and he would miss the 24 Hours of Le Mans.
In 2012, Lahaye competed in the FIA World Endurance Championship in OAK's Morgan LMP2 alongside Nicolet and Olivier Pla.
