Campo de’ Fiori is a rectangular square south of Piazza Navona in Rome, Italy, at the border between the rioni Parione and Regola. It is diagonally southeast of the Palazzo della Cancelleria and one block northeast of the Palazzo Farnese. The name dates to the Middle Ages when the area was a meadow.
