Baseball isn’t just a sport — it’s a lifestyle, a generational bond, and in some cases, a downright obsession. Some teams have fans who show up no matter what (even when their team is mathematically eliminated by June), while others only get loud when October rolls around.
So, which Major League Baseball fanbases are the most loyal? We’ve ranked the top 15 based on passion, unwavering support, and their ability to endure heartbreak without jumping ship.
15. Seattle Mariners
Seattle hasn’t seen a World Series appearance (ever), but Mariners fans keep showing up, rain or shine (mostly rain). Their dedication to King Félix, Ichiro, and the never-ending hope of returning to the playoffs is unmatched.
14. Texas Rangers
The Rangers finally broke through with their first World Series title in 2023, but their fans have been riding the highs and lows (mostly lows) for decades. From heartbreak in 2011 to the lean years that followed, Texas fans stuck around — and now, they’ve been rewarded.
13. Cincinnati Reds
Reds fans are passionate about their baseball history, even if recent years have been… well, less than ideal. They still pack Great American Ball Park and will argue with you about Pete Rose until the end of time.
12. Baltimore Orioles
The O’s went through some tough stretches, but fans still showed up in orange and black. Now that the team is exciting again, Camden Yards is rocking like it’s the ‘90s all over again.
11. St. Louis Cardinals
Cardinals fans love to remind you that they’re “the best fans in baseball,” and while that’s up for debate, there’s no denying their commitment. They expect excellence but will always fill Busch Stadium, win or lose.
10. Detroit Tigers
Tigers fans are tough. They survived a 119-loss season in 2003, an up-and-down rebuild, and heartbreak in the 2012 World Series. Through it all, they keep showing up, hoping for another Verlander-esque ace to bring them back to glory.
9. Chicago White Sox
South Side fans are a different breed. They don’t care about Wrigleyville, trendy rooftops, or national attention. They just want hard-nosed baseball, and they’ll let you know when they’re not getting it (which is often).
8. San Francisco Giants
From the Barry Bonds era to the dynasty years of the 2010s, Giants fans have always been all in. Oracle Park is packed, whether the team is a contender or playing .500 ball. Bonus points for surviving the torture of so many one-run games.
7. New York Mets
The Mets are the ultimate “love-hate” experience, but their fans never waver. They’ve endured collapses, front-office disasters, and bizarre injuries (looking at you, Cespedes and your wild boar incident), yet they keep coming back for more.
6. Boston Red Sox
The Sox went from being the ultimate underdogs to one of the most dominant teams of the 21st century. But whether they’re winning or bottoming out, Fenway is full of passionate fans ready to argue about the best place to get a lobster roll.
5. Philadelphia Phillies
Phillies fans boo Santa Claus, but they also fill Citizens Bank Park with an energy that’s unmatched. Love them or hate them, you can’t question their loyalty — especially after the rollercoaster seasons they’ve endured.

4. Chicago Cubs
The Cubs’ fanbase is one of the most loyal in sports, suffering through a 108-year drought before finally winning it all in 2016. Wrigley Field is always packed, whether they’re in first place or dead last.

3. Los Angeles Dodgers
Some say Dodgers fans show up late and leave early, but let’s be real: they still sell out nearly every game. Dodger Blue runs deep, and their fans travel well — seriously, have you seen how many Dodgers fans invade other ballparks?

1. New York Yankees
Say what you will about Yankees fans, but they show up. Whether they’re celebrating championships or calling for the manager’s head in April, their passion is unwavering. Yankees fans expect excellence and will never settle for less — making them, for better or worse, the most loyal fanbase in baseball.
