It is a weird thing, being the most hated team in the country. If you walk into a bar in Ann Arbor, Los Angeles, or even a tiny town in the middle of Indiana, you’ll find people who track rivals Notre Dame football fans with a level of obsession usually reserved for tax audits. The Irish don't have a conference. They don't have a single "designated" rival like Auburn has Alabama. Instead, they have a rotating cast of characters who all think they are the protagonist in Notre Dame's story.
It’s personal.
Honestly, the schedule is basically a "Who's Who" of programs that have spent a century trying to prove the Golden Dome is overrated. You’ve got the heavyweights like USC and Michigan, but then you’ve got these strange, deep-seated grudges with schools like Navy or Purdue that just won't go away. Some people think the USC game is the only one that counts. They’re wrong.
The USC Conflict: Why This is the Only "True" Rivalry
If you ask a donor in a green blazer who the biggest rival is, they’ll say USC every single time. It started because of a conversation between wives—literally. Back in the 1920s, Knute Rockne’s wife, Bonnie, allegedly convinced him that a trip to sunny Southern California every other year was better than playing in a snowstorm.
Since then, it has become the greatest intersectional rivalry in the sport. There is no trophy quite like the Jeweled Shillelagh. It’s a foot-long club made of Irish blackthorn, and every time someone wins, they add a little ornament. A ruby Trojan head for USC, an emerald shamrock for Notre Dame.
What makes this rivalry different from, say, Michigan vs. Ohio State, is the lack of proximity. These schools are 2,000 miles apart. Yet, the stakes are almost always national. Think back to 2005. The "Bush Push." Matt Leinart fumbles out of bounds, the clock should have run out, but Charlie Weis is already celebrating. Then, Matt Bush pushes Leinart into the end zone. It broke Notre Dame fans. People still talk about that game in South Bend like it was a literal crime scene.
But USC isn’t just about the past. In the modern era of the Transfer Portal and NIL, these two are fighting for the same five-star recruits from Mater Dei and St. John Bosco. When Lincoln Riley took the USC job, the temperature went up. Notre Dame fans look at the flashy, high-scoring Trojans and see everything they hate—glitz, glamour, and a perceived lack of "grit." USC fans look at Notre Dame and see a bunch of self-righteous Midwesterners living in the 1940s.
The Michigan Problem: It’s Not Just About Football
If USC is a respectful, high-stakes chess match, Michigan is a bar fight.
There is genuine, documented dislike here. It goes back to Fielding Yost, the legendary Michigan coach who essentially blackballed Notre Dame from joining the Big Ten because he didn't like Catholics. That isn't some message board conspiracy theory; it’s historical fact. Yost's pettiness is why Notre Dame remained an independent for so long.

The rivalry has been played in fits and starts. They didn't play for decades, then they played every year, and now it’s back to being an occasional treat. Every time they meet, the "Under the Lights" energy is unmatched. Who can forget 2011? Denard Robinson basically willed Michigan to a comeback victory in the final seconds. It was chaotic. It was loud. It was exactly why we watch this sport.
A lot of people think Michigan is the primary rival. They aren’t. They are the antagonist. Notre Dame fans want to beat USC because it means they are the best in the country. They want to beat Michigan because they just want Michigan to lose.
Navy: The Rivalry That Isn't a Rivalry
You cannot talk about rivals Notre Dame football without mentioning the Midshipmen. This is the most respectful "rivalry" in sports. During World War II, Notre Dame was on the brink of financial collapse because all the young men were off at war. The Navy stepped in, established a training center on campus, and paid the school enough to keep the lights on.
Notre Dame has never forgotten that.
The Irish have promised to play Navy every year as long as Navy wants to play. For a long time, it was a blowout. Notre Dame won 43 straight games from 1964 to 2006. It wasn't even competitive. But then, in 2007, Navy broke the streak in triple overtime. Since then, the Triple Option has been a nightmare for Irish defensive coordinators. It’s a game where you win, but your linebackers come home with bruised knees and turf burn.
The Regional Grudges: MSU, Purdue, and Stanford
Then you have the "trophy games."
Notre Dame plays for a lot of weird stuff.
The Megaphone Trophy (Michigan State).
The Shillelagh Trophy (Purdue).
The Legends Trophy (Stanford).
Purdue is the "spoiler." No matter how good Notre Dame is, a trip to West Lafayette in September is a trap. It’s a "little brother" dynamic that Purdue leans into with massive success. They’ve ruined more undefeated Notre Dame seasons than almost any other program.
Michigan State is different. That rivalry peaked in the 1960s with the "Game of the Century" in 1966—a 10-10 tie that still makes people angry today. Ara Parseghian chose to run out the clock rather than risk a turnover, and people called him a coward for it. It was two of the best teams to ever step on a field, and neither won.

Stanford is the new kid on the block. It’s an academic rivalry as much as a football one. Both schools pride themselves on being "elite" in the classroom. When Jim Harbaugh was at Stanford, he made it his mission to bully Notre Dame. He succeeded. Now, with both programs in different spots, the heat has died down a bit, but the desire to prove who the real "academic powerhouse" is remains.
The ACC Agreement: Forging New Enemies
Since Notre Dame joined the ACC for everything except football, they play five ACC teams a year. This has created "mini-rivalries" that didn't exist twenty years ago.
Florida State and Clemson are the big ones.
The 1993 "Game of the Century" against FSU is still the gold standard for South Bend atmospheres. When Clemson comes to town, it feels like a playoff game. The 2020 double-overtime win against a top-ranked Clemson (even without Trevor Lawrence) was a seminal moment for the Brian Kelly era. These aren't "traditional" rivals, but they are the games that define the modern schedule.
What Most People Get Wrong About the Rivalries
There's a misconception that Notre Dame is "ducking" teams by being independent.
Actually, it's the opposite.
Being independent allows them to maintain these rivals across the country. If they joined the Big Ten, they’d lose the USC game or the Navy game eventually. The schedule is a delicate balancing act. You have to play the Midwest schools for the local fans, the California schools for recruiting, and the ACC schools for the legal contracts.
Another myth: "Nobody cares about the Navy game."
Tell that to the 80,000 people who show up when they play in Dublin or at a NFL stadium. It's about tradition. In college football, tradition is the only currency that actually matters when the money gets too big.

Why the Landscape is Shifting in 2026
We are currently in the middle of a massive shift. The Big Ten and SEC are swallowing everyone. USC is in the Big Ten now. This changes everything. Suddenly, the Notre Dame-USC game isn't just an "intersectional" clash; it's a game between an Independent and a Big Ten powerhouse.
It makes the game even more important for Notre Dame’s survival as an independent. If they can’t beat the big boys in the Big Ten, the pressure to join a conference will become unbearable.
Actionable Insights for Fans and Analysts
If you are trying to understand the hierarchy of Notre Dame’s opponents, look at the scheduling frequency and the historical "why" behind the game.
- The "Must-Wins": USC and Michigan. These are the identity games. Losing both in a season is considered a failure, regardless of the final record.
- The "Trap" Games: Purdue and Boston College. BC is the "Holy War." As the only two major Catholic universities in the FBS, there is a level of pettiness there that defies logic.
- The "Respect" Games: Navy. It’s about the anthem, the flyover, and the history.
To stay ahead of the curve on these rivalries, keep an eye on recruiting trails in Southern California and South Florida. That is where these games are actually won. When a kid from Los Angeles chooses South Bend over LA, it adds fuel to the fire for the next decade.
Watch the coaching carousels, too. Marcus Freeman has a different approach to these rivalries than Brian Kelly did. He’s more aggressive, more "modern." Whether that translates to more trophies in the case remains to be seen, but the intensity isn't going anywhere.
The reality of rivals Notre Dame football is that every game is a rivalry to the other team. When you have the golden helmet, you are everyone's Super Bowl. That is the burden of the program. It’s also why, even when they aren't winning championships, they are still the most talked-about team in the sport.
If you want to experience it, go to South Bend in October when USC comes to town. Watch the Trumpets Under the Dome. Walk through the tailgates. You’ll realize quickly that these rivalries aren't just games; they are the lifeblood of the university's identity.
To truly track the progress of these matchups, monitor the updated NCAA "Strength of Schedule" rankings each August. Notre Dame's unique status often puts them in a position where their playoff hopes hinge entirely on how their rivals—specifically USC and their ACC opponents—perform in their own conferences. Following the "common opponents" metric is the best way to gauge where the Irish stand before the November stretch.
Check the historical records at the College Football Hall of Fame or the Notre Dame archives if you want to see the original letters between Rockne and the USC administration. It puts the modern animosity into perspective. These aren't just sports teams; they are institutions that have been locked in a cold war for a century.
And it's not ending anytime soon.
