The Quadrilatero della moda (Italian pronunciation: [kwadriˈlaːtero della ˈmɔːda]; literally "fashion square"), or Via Montenapoleone fashion district, is a shopping district in the centre of the Italian city of Milan. Shops there include both Italian fashion and international brands.

The sides of the square, located to the south of the arches of Porta Nuova, are formed by Via Montenapoleone (SW), Via Manzoni (NW), Via della Spiga (NE), and Corso Venezia (SE).

Streets inside this area include Via Borgospesso, Via Santo Spirito, Via Gesù, Via Sant'Andrea, Via Bagutta, and Via Baggutino. The zone extends in practice also to the north-west of Via Manzoni with Via Pisoni, and to the south and west of Via Montenapoleone with Corso Giacomo Matteotti (this last meets Corso Venezia at Piazza San Babila), Piazza Meda, Via San Pietro all'Orto, and Via Verri.
