There are losses that hurt because of what was at stake.
There are losses that expose a team.
Then there are the losses that become permanent reference points that are brought up years later whenever something goes wrong.
Penn State has experienced all three over the last decade.
Some came against elite opponents and were remembered because of how thoroughly Penn State was beaten. Others came against teams the Nittany Lions had no business losing to.
Friday night’s 34-13 loss at Northwestern earned its way into that conversation, but it still has competition for the most painful defeat of the era.
Here are Penn State’s five worst losses of the last decade.
No. 5 Michigan 42, Penn State 7 – 2018
Penn State had already suffered heartbreaking losses to Ohio State and Michigan State when it arrived in Ann Arbor, but nothing suggested the Nittany Lions would be dismantled quite like this.
Michigan won 42-7, and the game wasn’t as competitive as the score.
Penn State didn’t score until Tommy Stevens’ touchdown run with 1:59 remaining. Trace McSorley threw for only 83 yards, and Michigan turned a 14-0 halftime advantage into a 42-0 rout before the meaningless late touchdown.
This wasn’t an upset. Michigan was a legitimate College Football Playoff contender.
What made it memorable was the physical disparity.
James Franklin had elevated Penn State back into the national conversation, winning the Big Ten in 2016 and going 11-2 in 2017. The expectation was that Penn State could line up with anybody.
Michigan made Penn State look like it didn’t belong on the same field.
No. 4 Northwestern 34, Penn State 13 – 2026
The Matt Campbell era is only beginning, but Friday night’s performance already owns an unwanted place in Penn State history.
Northwestern didn’t steal a game with turnovers or a late touchdown.
The Wildcats dominated Penn State physically.
Northwestern rushed for 413 yards, its highest total since 2003, while Caleb Komolafe and Joseph Himon II combined for 350. The Wildcats never trailed in the first game at the rebuilt Ryan Field.
That’s what puts this loss here.
Penn State entered the night needing a response after blowing a 17-point lead in a 24-20 home loss to Wisconsin. Instead, the Nittany Lions fell behind 24-7 by halftime and 31-7 before the fourth quarter.
The final score was ugly.
The manner in which it happened was worse.
Penn State was pushed around at the line of scrimmage by a program it expects to beat. For a Campbell team whose identity is supposed to be rooted in toughness and physical football, allowing more than 400 rushing yards is the type of performance that immediately becomes a measuring stick for everything that follows.
No. 3 Michigan 41, Penn State 17 – 2022
The scoreboard doesn’t fully explain this one.
The statistics do.
Penn State arrived in Ann Arbor 5-0 and ranked No. 10, giving Franklin another opportunity to prove his program belonged alongside the Big Ten’s elite.
For a while, the Nittany Lions survived. Curtis Jacobs returned an interception for a touchdown, and Penn State actually led 17-16 during the third quarter.
Then Michigan erased any illusion of competitiveness.
Donovan Edwards broke a 67-yard touchdown run. Blake Corum followed with a 61-yarder. Michigan scored the game’s final 25 points and finished with 418 rushing yards. Penn State managed only 268 total yards.
Penn State eventually finished 11-2 and won the Rose Bowl, which proved this was a very good football team.

A team capable of winning 11 games was completely overwhelmed by the opponent Penn State needed to beat to reach another level.
No. 2 Illinois 20, Penn State 18 – 2021
Few Penn State games have ever been stranger.
No. 7 Penn State entered as a heavy favorite against Illinois. Instead, the Nittany Lions became part of history for all the wrong reasons in the first nine-overtime game in college football history.
Penn State led 10-0 but couldn’t put Illinois away. The Illini tied it in the fourth quarter, the teams exchanged field goals in the first two overtimes, and what followed was an almost surreal exchange of failed two-point conversions.
Illinois finally won when Brandon Peters connected with Casey Washington in the ninth overtime.
The circumstances made it even worse after Illinois only threw for 38 passing yards and gauged a wounded Nittany Lion defense for 357 yards on 67 carries.
Penn State had started 5-0 before losing at Iowa, where Sean Clifford was injured. Clifford returned against Illinois but clearly wasn’t operating at his best.
Still, this was Illinois with a first-year head coach Bret Bielema at home with a No. 7 ranking.
The Nittany Lions had championship aspirations earlier that month.
After nine overtimes against Illinois, those aspirations were gone.
No. 1 UCLA 42, Penn State 37 – 2025
There have been bigger blowouts.
There may never be a more inexplicable Penn State loss.
Penn State entered the Rose Bowl ranked No. 7. UCLA entered 0-4.
The Bruins had already fired offensive coordinator Tino Sunseri, and head coach DeShaun Foster had been fired in September. UCLA looked like one of the worst Power Four teams in America.
UCLA turned to Jerry Neuheisel to coordinate the offense and he was able to deliver the ultimate shocker having the Bruins go up 27-7 on Penn State before anything even registered.
The Bruins cut through a much maligned Nittany Lions defense like a hot knife through butter.
UCLA quarterback Nico Iamaleava demonstrated shades of Vince Young with 294 yards of total offense (166 pass, 128 rush) and five total touchdowns (2 pass, 3 rush).
The Nittany Lions eventually rallied, cutting the deficit and turning what appeared destined to become a blowout into a game. Drew Allar threw for 200 yards and ran for another 78, while Penn State accumulated 357 total yards.
It didn’t matter.
UCLA won 42-37 for its first victory of the season
In retrospect, it was even more consequential than it seemed that afternoon. Penn State’s 2025 season spiraled from there, with the UCLA defeat becoming part of a six-game losing streak that included losses to Northwestern and Iowa.
That’s what separates UCLA from the others.
Michigan in 2018 embarrassed Penn State. Michigan in 2022 exposed the gap between the Nittany Lions and the Big Ten’s best. Illinois produced one of the strangest defeats in program history. Northwestern physically dismantled Penn State Friday night.
UCLA shattered the trajectory of an entire season and program as the catalyst for athletic director Pat Kraft to begin exploring moving on from James Franklin.
For Neuheisel, he was celebrated as a conquering hero. This game wasn’t the only game where Neuheisel played a role in stunning the Nittany Lions. He is now on Northwestern’s staff as the quarterbacks coach and being mentored by offensive coordinator Chip Kelly.
For Penn State it went to Pasadena expecting to correct itself after a double-overtime loss to Oregon.
Instead, an 0-4 team exposed problems that proved far bigger than one bad Saturday.
And until something even more stunning happens, that’s the standard against which Penn State’s worst losses of the modern era will be measured.
