Claude Mauriac (25 April 1914, Paris – 22 March 1996) was a French author and journalist, the eldest son of the author François Mauriac.
He was the personal secretary of Charles de Gaulle from 1944 to 1949, before becoming a cinema critic and arts person of Le Figaro.
He was the author of several novels and essays, and co-scripted the movie adaptation of his father's novel Thérèse Desqueyroux.
He also wrote a study of the novelist Marcel Proust, his wife's great-uncle.
Mauriac was also a close friend of French philosopher Michel Foucault.
Mauriac is perhaps most famous for being Simone de Beauvoir's primary example of 'disarming masculine naïveté" in the introduction to her seminal feminist text, The Second Sex.
Quoting Mauriac's misogynistic writing, de Beauvoir asserts on Mauriac's behalf that "no one is more arrogant towards women, more aggressive or more disdainful, than a man anxious about his own virility".
