René d'Herblay, alias Aramis, is a fictional character in the novels The Three Musketeers (1844), Twenty Years After (1845), and The Vicomte de Bragelonne (1847–1850) by Alexandre Dumas, père.

Eventually, he is named Superior General of the Jesuits, which is precisely what saves his life at the end of Le Vicomte De Bragelonne, after he is betrayed by Nicolas Fouquet.

In Twenty Years After, he follows Athos's pleas to spare the life of the villain Mordaunt, and in Le Vicomte De Bragelonne, he refuses to suppress d'Artagnan's discovery of the truth about Belle-Île-en-Mer.

Friendship is so important to Aramis that, at the end of Le Vicomte De Bragelonne, it is strongly implied that he cries - for the first and only time in his life - after causing the death of one of his friends.

In The Vicomte de Bragelonne he is the Bishop of Vannes, a title given to him by Nicolas Fouquet, and later becomes the Superior General of the Jesuits.
