Augustin Pajou (19 September 1730, Paris – 8 May 1809) was a French sculptor, born in Paris. At eighteen he won the Prix de Rome, and at thirty exhibited his Pluton tenant Cerbère enchaîné (now in the Louvre).
Pajou's portrait busts of Buffon and of Madame du Barry (1773), and his statuette of Bossuet (all in the Louvre), are amongst his best works.
When Bernard Poyet constructed the "Fontaine des Innocents" from the earlier edifice of Pierre Lescot, Pajou provided a number of new figures for the work. Mention should also be made of his bust of Carlin Bertinazzi (1763) at the Comédie Française, and the monument to Marie Leszczyńska, Queen of France (in the Salon of 1769). Pajou was one of the main artists whose work was included in the collection of the Comédie-Française at the end of the 18th century. Others were Jean-Baptiste d'Huez, Jean-Joseph Foucou, Simon-Louis Boizot and Pierre-François Berruer. Pajou was commissioned by Napoleon to make the copies of the Medici Lions now situated in the garden of the Villa Medici 1803. Pajou died in Paris on 8 May 1809.
