Stadio Gino Alfonso Sada, Football stadium in Monza, Italy.

Stadio Gino Alfonso Sada is a football stadium in Monza with stands arranged around a field covered in artificial grass. The venue can hold around 2,000 spectators and sits on Via Guarenti near the city center.

The stadium opened in October 1945 with a friendly match between Monza and Pavia, marking football's return after World War II. It received its current name in 1965 to honor Gino Alfonso Sada, a president of Monza's football club.

Fans kept calling the ground "San Gregorio" even after it was officially renamed Stadio Città di Monza in 1953, and the name stuck until 1965. Behind today's parking area stands the small chapel of San Gregorio, the last remnant of the cemetery that once occupied the site. The ground now hosts the women's team Fiammamonza and Juvenilia.

Only the recently renovated covered tribuna is in use, seating up to 2,000; the central and south stands have been closed since 1988 and the north stand was demolished for an internal car park. The pitch is artificial turf. The ground lies near Monza's station, but its tight access roads in the centre made policing visiting fans difficult in the past.

Behind the stadium's parking area stands the Cappelletta di San Gregorio, a small chapel that once marked the far end of the San Gregorio cemetery, decommissioned in the late 19th century. The ground itself was laid out on the former parade ground of the Gioventù Italiana del Littorio, inaugurated by Mussolini in 1930.
