Claude Vasconi (24 June 1940 – 8 December 2009) was a French architect.
Vasconi was born in Rosheim, and was educated at the Ecole Nationale Supérieure des Arts et de l'Industrie in Strasbourg.
After designing two key projects as a young architect, Forum des Halles in the centre of Paris and the building of the Préfecture in Cergy-Pontoise, he became one of the most sought-after architects in France, with major projects in Montpellier, Strasbourg and Saint-Nazaire.
He died in Paris, aged 69.
Claude Vasconi has been credited as the pioneer proponent of the concept of "Angelina"-style cellular steel beams.
