Thierry Lhermitte (born 24 November 1952) is a French actor, known for his comedic roles. He was one of the founders of the comedy troupe Le Splendid in the 1970s, along with, among others, his high-school friends Christian Clavier, Gérard Jugnot, and Michel Blanc. That group adapted a number of its stage hits for the cinema, and scored major successes with films such as Les bronzés (1978), Les bronzés font du ski (1979) and Le Père Noël est une ordure (1982).
He has also had a successful career away from Le Splendid, particularly with the films Les ripoux (1984), La Totale! (1990; remade as True Lies with Arnold Schwarzenegger in Lhermitte's role) and Le Dîner de Cons (1998, with the late Jacques Villeret), among many others.
In 2010 he played the title role in the French remake of Doc Martin, Docteur Martin.
