Christophe-Gabriel Allegrain (11 October 1710 - 1795) was a French sculptor who tempered a neoclassical style with Rococo charm and softness, under the influence of his much more famous brother-in-law, Jean-Baptiste Pigalle.
Allegrain was born into a well-established family of landscape painters in Paris.
His single most famous work, a marble Bather (La Baigneuse), was commissioned for the royal residences through the Bâtiments du Roi in 1755; a modelled sketch was shown at the Salon of 1757.
