The Section d'Or ("Golden Section"), also known as Groupe de Puteaux (or Puteaux Group), was a collective of painters, sculptors, poets and critics associated with Cubism and Orphism. Based in the Parisian suburbs of Puteaux and Courbevoie, the group was active from 1911 to around 1914, coming to prominence in the wake of their controversial showing at the Salon des Indépendants in the spring of 1911.
