The list of AC Milan rivals runs far beyond the two obvious names: Inter Milan share the city and the stadium, Juventus contest the historical bragging rights, Napoli carry the scars of the great late-1980s title races, and Genoa, Atalanta, Roma, Fiorentina and even Liverpool all bring their own grudges. This guide covers every rivalry that matters, with the records behind each one.
Seven of these opponents visit San Siro every season in Serie A, so the fixtures below are bookable months in advance. Derby and Juventus dates sell through first.
Inter Milan: one city, one stadium, one grudge
The Derby della Madonnina is the rivalry that defines the club. It takes its name from the golden statue of the Madonna on top of Milan's cathedral, and it exists because of a divorce: Inter Milan was founded in 1908 by members who broke away from the original Milan club in a dispute over signing foreign players. The first competitive meeting followed in January 1909, a 3-2 win for the Rossoneri, and the two have never left the same city or the same ground since.
Inter hold a narrow historical lead. Across 246 competitive meetings through the end of the 2025-26 season, Inter have won 91, Milan 84, with 71 drawn (source: Wikipedia, Derby della Madonnina record). The fixture has produced genuine extremes: an 11-goal derby in 1949 that finished 6-5 to Inter, and Milan's record 6-0 away win in May 2001. One quieter fact stands out too. Since 1980 the two sets of ultras have held a non-aggression understanding, agreed after a young Inter supporter died in post-match clashes, which is why the loudest derby in Italy is also one of its safest.
The current momentum is red and black. Milan completed a league derby double in 2025-26, winning 1-0 away in November 2025 through Christian Pulisic and 1-0 at home in March 2026 through Pervis Estupinan, the club's first double over Inter since 2011 (source: ESPN match reports). That run stretched Inter's winless streak in the fixture to seven, a sore point in a season Inter otherwise owned by winning their 21st Scudetto.
Juventus: the fight for Italy's crown
If the derby is personal, Juventus is institutional. This is the clash between the club with the most Serie A titles, 36 for the Bianconeri, and the Italian club with the most European Cups, seven for Milan (source: Wikipedia and acmilan.com). Juventus are also the opponent Milan have faced more than any other, and the all-time ledger favours Turin: roughly 94 Juventus wins to 71 for Milan across all competitions, with the Serie A-only record reading 69 wins to 53 with 60 draws (source: RSSSF and acmilan.com; totals vary slightly between providers depending on pre-war matches).
The fixture has decided Scudetti, Coppa Italia ties, Supercoppa finals and even the 2003 Champions League final, which Milan won on penalties at Old Trafford after a goalless draw. Recent meetings have kept the tension and lost the goals: both 2025-26 league games at the Milan vs Juventus fixture and its reverse finished 0-0, with Pulisic missing a penalty in Turin in October 2025 (source: ESPN). There is a managerial subplot too, since Massimiliano Allegri returned to the Milan bench in May 2025 after eight years and two spells at Juventus, who themselves replaced Igor Tudor with Luciano Spalletti in October 2025 (source: CBS Sports and Fox Sports).
Napoli: north against south
The rivalry with Napoli was forged in the late 1980s, when Serie A was the strongest league in the world and its two best teams were Diego Maradona's Napoli and Arrigo Sacchi's Milan of Ruud Gullit, Marco van Basten and Frank Rijkaard. The 1987-88 title race remains the reference point: Napoli led by four points with five rounds to play, then collapsed, and Milan sealed the Scudetto by winning 3-2 in Naples on the run-in (source: The National and contemporary reports). Beneath the football sat Italy's oldest fault line, the industrial north against the proud south, which gave every meeting an edge no other Milan fixture carries.
The modern version has real stakes again. Napoli won Scudetti in 2023 and 2025, Milan answered with the 2022 title, and the two have traded blows in recent Champions League and Serie A meetings while both chase Inter. Milan hold a modest all-time edge in wins, but the Stadio Diego Armando Maradona has become one of the hardest away grounds in the division.

Genoa: the rivalry born from tragedy
On the pitch, Milan dominate Genoa: the Rossoneri have lost only a handful of the last several decades' meetings and have won the large majority of recent encounters. Off the pitch, this is the most bitter relationship Milan's support has with any club, and it dates to one specific day. On 29 January 1995, Genoa supporter Vincenzo Spagnolo was stabbed to death outside the Stadio Luigi Ferraris by a Milan ultra before the match, which was abandoned goalless at half-time; the Italian authorities suspended the entire national sporting programme the following weekend (source: The Washington Post, 30 January 1995).
The consequences lasted a generation. Away supporters from each club were barred from the other's stadium until 2010, and the fixture is still policed as a high-risk match today. It is a rivalry defined not by trophies but by memory, and Genoa's Gradinata Nord has never let it fade.
Atalanta: the neighbour that grew teeth
Bergamo sits less than an hour from Milan, and Atalanta's Curva Nord is among the most hostile in Italy. The enmity is rooted in old fan alliances rather than title races, but the football caught up in the Gian Piero Gasperini years, when Atalanta turned from a yo-yo club into a Champions League regular and a Europa League winner in 2024. Milan still lead the historical head-to-head comfortably, yet the balance has shifted: Atalanta won both league meetings in 2024-25, only the third time they have managed that in their history after 1940-41 and 2007-08 (source: Opta via FotMob).
For travelling Milanisti this is now one of the loudest and least comfortable away days in Serie A, which is exactly what makes it worth doing once.
Roma: capital against capital of the north
Milan against AS Roma is a rivalry of status rather than geography. Both see themselves among Italy's grandest institutions, the fixture regularly shapes the race for Champions League places, and the atmosphere between San Siro's Curva Sud and Rome's Curva Sud has carried real needle since the 1980s and 1990s, when the clubs traded Scudetti and cup finals. The 2003 Coppa Italia final between the two, won by Milan over two legs, sits alongside countless league deciders in the shared memory.
Recent seasons have kept the fixture relevant, with the sides repeatedly meeting in the top-four run-in and in the 2023-24 Europa League quarter-final, which Milan lost over two legs, a result Roma's support has not allowed anyone to forget.
Fiorentina: the purple grudge
Ask a Fiorentina supporter about Milan and the answer usually involves the word arrogance. Florence has long resented the wealth and pull of the big northern clubs, and the feeling sharpened in the 1990s when Milan repeatedly beat the Viola to honours and later signed away favourite sons. The fixture has produced regular upsets at the Stadio Artemio Franchi, where Milan's record over the decades is noticeably weaker than against most mid-table opposition.
It is a second-tier rivalry by Milanese standards but a first-tier one by Florentine standards, which is precisely the imbalance that keeps it spiky.
Liverpool: the European wound and the revenge
No foreign club looms larger in Milanese memory than Liverpool. The 2005 Champions League final in Istanbul saw Milan lead 3-0 at half-time through Paolo Maldini and Hernan Crespo, concede three in six second-half minutes and lose the shoot-out 3-2, with Jerzy Dudek saving from Andriy Shevchenko (source: UEFA). Two years later in Athens, Milan won the rematch 2-1 with both goals from Filippo Inzaghi, a night the club treats as the settling of a debt rather than a mere seventh European Cup (source: UEFA and Wikipedia).
The clubs met again in the 2021-22 group stage, when Liverpool won narrowly at both Anfield and San Siro, and every renewal since has sold out on the strength of those two finals alone.
San Siro: the stage every rival visits
Every rivalry above passes through the same address. San Siro, formally the Stadio Giuseppe Meazza, is Italy's largest ground and the only stadium in Europe's top leagues shared by two clubs of this size. Its final chapter is now written: Milan and Inter completed the purchase of the stadium and surrounding land from the city in November 2025 for a deal valued at 197 million euros, and plan a new 71,500-seat arena designed by Foster + Partners and MANICA, targeted for completion before Euro 2032 (source: ESPN and Goal.com). If you want to see a derby in the old bowl, the window is closing, and it is worth studying the San Siro seating plan before choosing a tier.
Which rivalry should you watch first?
For atmosphere, the derby against Inter is untouchable. For history, take Juventus. For hostility, Atalanta away or Genoa at the Ferraris. For romance, wait for a European draw against Liverpool. All of them run through the 2026-27 calendar, and our top five leagues season preview sets out how the new Serie A season shapes up.
