Bernardo Antonio Vittone (19 August 1704 – 19 October 1770) was an Italian architect and writer. He was one of the three most important Baroque architects active in the Piedmont region of Northern Italy; the other two were Filippo Juvarra and Guarino Guarini. The youngest of the three, Vittone was the only one who was born in the Piedmont. He achieved a synthesis of the spatial inventiveness of Juvarra and the engineering ingenuity of Guarini, particularly in the design of his churches, the buildings for which he is best known.
