Piazza Napoleone, Historic square in Lucca, Italy.

Piazza Napoleone is Lucca's main square, a broad, level expanse of grey gravel and packed earth. The Palazzo Ducale occupies the entire western side, while the south opens onto Piazza del Giglio and the Teatro del Giglio. At the centre stands Lorenzo Bartolini's 1843 monument to Duchess Maria Luisa of Bourbon.

The square opened in 1806 under Elisa Bonaparte Baciocchi, Napoleon's sister and princess of Lucca, who had houses, shops, salt warehouses and the church of San Pietro Maggiore demolished to open space before the Palazzo Ducale. Her plan for a colossal statue of Napoleon ended with the Congress of Vienna in 1815; Maria Luisa of Bourbon instead placed Lorenzo Bartolini's monument to herself here in 1843.

The square's name comes from Napoleon, honoured by Elisa Bonaparte Baciocchi, who had it laid out in 1806. Since 1998 the Lucca Summer Festival has brought Italian and international stars here each summer, between June and July. In December a Christmas market fills the square, with an ice rink and a vintage carousel until the Befana feast; stalls return at Easter and in September for the Santa Croce festival.

The square sits about 650 meters from Lucca's main railway station and is easy to reach on foot. Multiple bus stops serving local lines are located near the plaza, making it accessible by public transport.

Glass blocks embedded in the pavement create windows into archaeological remains of structures demolished during the Napoleonic era. These see-through floor panels were discovered during 1998 excavations and reveal the buried past directly beneath visitors' feet.
