Let’s be real—every MLB fanbase has that thing that makes them stand out. Some are charming, some are downright unbearable, and some have perfected the art of making the entire league collectively roll their eyes.
Now, we’re not here to launch a 100-mph fastball of pure disdain, but we are ready to stir the pot and embrace the beautiful chaos that is baseball fandom. So grab your peanuts, Cracker Jack, and maybe some earplugs—because these are the 15 most insufferable MLB fanbases, ranked with plenty of love (and just a little side-eye).
15. Seattle Mariners
Let’s start with the Pacific Northwest. Mariners fans have perfected the art of the sad-yet-hopeful underdog. Sure, they’ve been through decades of heartbreak, but does that really excuse their relentless optimism? Also, let’s not forget that they won’t shut up about Ichiro Suzuki. Yes, he’s a legend. No, we don’t need to hear about him again.
14. Cincinnati Reds
Reds fans are like your grandpa at Thanksgiving: always talking about the glory days. Yes, the Big Red Machine was incredible, but that was over 40 years ago. Plus, their annual Opening Day obsession feels like they’re compensating for the other 161 games where things usually go sideways.
13. Milwaukee Brewers
Two words: beer snobs. Brewers fans will lecture you endlessly about their superior ballpark brew selection as if they’re connoisseurs at a fine dining establishment. We get it; you like craft beer. Meanwhile, the rest of us are just here to drink overpriced Bud Light and yell at umpires.
12. San Francisco Giants
Giants fans will never let you forget they won three World Series in five years (2010, 2012, 2014). They’ll bring it up in conversations that have absolutely nothing to do with baseball. Also, if you’ve ever been to Oracle Park, you know they’re insufferably smug about their views of the Bay. Yes, it’s gorgeous. No, we don’t care.
11. Cleveland Guardians
Guardians fans have an almost masochistic loyalty to their team, despite a championship drought stretching back to checks notes 1948. Their self-deprecating humor is funny at first, but after the 10th “Maybe next year” joke, you start to wonder if they’re okay. Spoiler: they’re not.
10. Texas Rangers
Rangers fans have spent years living in the shadow of the Astros, which has turned their inferiority complex into a full-blown personality trait. And let’s not even talk about how salty they still are about 2011. Hint: David Freese still lives rent-free in their heads.
9. Philadelphia Phillies
If “passion” were a fanbase, it’d be Phillies fans. They’ll boo their own players, throw snowballs at Santa Claus, and somehow make you feel like it’s your fault. Don’t get us wrong, they love their team. They just hate everything else.
8. Boston Red Sox
Remember when Red Sox fans were the lovable underdogs of baseball? Yeah, that ship sailed in 2004. Now, they’re just Yankees fans in disguise: loud, entitled, and quick to remind you how many rings they’ve won in the past two decades.
7. Chicago Cubs
Winning the World Series in 2016 didn’t humble Cubs fans—it turned them into monsters. They’ve traded in their “Lovable Losers” status for “We Deserve to Win” energy, and the constant “Wrigley is a cathedral” takes aren’t helping their case.
6. St. Louis Cardinals
The self-proclaimed “Best Fans in Baseball” are anything but. Cardinals fans love to flaunt their “classiness” while simultaneously acting like sore losers every time the team falls short. Plus, the Midwest nice act? We’re not buying it.

5. Los Angeles Dodgers
Dodgers fans — or at least the ones who actually show up before the third inning — are some of the most obnoxious in the league. From their constant bragging about payrolls to the Hollywood glitz-and-glamour vibe, they’re easy to root against. And don’t even get us started on the beach balls in the outfield.

4. Atlanta Braves
Braves fans might not seem that bad on the surface, but spend any time at Truist Park, and you’ll see why people don’t like them. The Tomahawk Chop? Yeah, it’s 2025, and we’re still doing that? Also, their “sellout” energy comes off as insincere. Are they even that passionate, or are they just there for the Instagram photos?

3. New York Mets
Mets fans are the ultimate contradiction: perpetually miserable yet incredibly cocky. They’ll remind you of their past heartbreaks one second and then act like they’re destined for a World Series the next. Pick a lane, Mets fans!

2. Houston Astros
Even if you’re an Astros fan, you know why they’re here. The 2017 sign-stealing scandal turned them into baseball’s ultimate villains, and their fans’ refusal to acknowledge it doesn’t help. Pro tip: stop telling us to “get over it.” We’re not going to.

1. New York Yankees
“27 rings.” That’s it. That’s the tweet. Yankees fans love to remind you of their historic success, as if they personally contributed to Babe Ruth’s home runs. Plus, they’re everywhere. You could be hiking in the Himalayas and still see someone in pinstripes yelling about Aaron Judge.
