Inter Milan U23

Football Club Internazionale Milano Under-23, known as Inter Milan Under-23 or simply Inter U23, is a professional football club based in Milan, Lombardy, Italy, which acts as the reserve team of Serie A club Inter Milan. Founded on 24 July 2025, the club competes in Serie C Group A and the Coppa Italia Serie C.

In February 2025, Inter Milan president Giuseppe Marotta announced the club's plans to launch a reserve team beginning with the 2025–26 season. The club, the fourth reserve team introduced in Italian football after Juventus Next Gen, Atalanta BC Under-23 and Milan Futuro, was formally admitted to Serie C on 24 July 2025, replacing the excluded SPAL. Stefano Vecchi was appointed as the inaugural head coach. The team trains at the Centro Sportivo Giacinto Facchetti, also known as Interello, which offers 30,000 square meters of professional training and education facilities between the Niguarda and Bresso neighborhoods in northern Milan.

The club plays its home matches at the Stadio Brianteo in the city of Monza, about 15 kilometres (9 miles) north-northeast of Milan.
