March 10th marks a special day for gamers and pop culture enthusiasts around the world: Mario Day! If you’re scratching your head wondering what this is all about, don’t worry—you’re not alone.
Mario Day is a fun, unofficial holiday dedicated to one of the most beloved characters in video game history: Mario, the plucky Italian plumber from Nintendo’s iconic franchise.
Let’s dive into what Mario Day is, why it’s celebrated, and how fans honor this pixelated hero.
What Is Mario Day?
Mario Day is celebrated every year on March 10th, a date chosen for a clever reason. When you write out “March 10” as “Mar10,” it visually resembles the word “Mario.”
This playful wordplay was first embraced by Nintendo and fans as a way to spotlight the character who has been jumping across screens and saving princesses since the 1980s. While it’s not an official public holiday (don’t expect a day off work!), it’s a lighthearted occasion recognized by gamers, collectors, and anyone who grew up with a Nintendo controller in hand.
The day serves as a tribute to Mario, the star of countless video games, and the broader Mario universe, which includes characters like Luigi, Princess Peach, Bowser, and Toad. It’s a chance for fans to celebrate the legacy of a character who has become a cornerstone of gaming culture.

The Origins of Mario
Mario first leaped into existence in 1981, created by legendary game designer Shigeru Miyamoto for Nintendo’s arcade game Donkey Kong. Back then, he wasn’t even called Mario—he was simply “Jumpman,” a carpenter trying to rescue a damsel from a barrel-tossing gorilla. It wasn’t until 1983’s Mario Bros., where he teamed up with his brother Luigi to battle sewer-dwelling enemies, that Mario got his name and plumber profession.
The real breakthrough came in 1985 with Super Mario Bros. for the Nintendo Entertainment System (NES). This groundbreaking platformer introduced the Mushroom Kingdom, power-ups like the Super Mushroom and Fire Flower, and a quest to rescue Princess Peach from the villainous Bowser. The game’s success catapulted Mario to superstardom, cementing his place as Nintendo’s mascot and a symbol of video gaming itself.
Since then, Mario has starred in dozens of games across multiple genres—platformers, racing (Mario Kart), sports (Mario Tennis), and even party games (Mario Party). His red cap, blue overalls, and cheerful “It’s-a me, Mario!” catchphrase are instantly recognizable worldwide.
Why March 10th?
The “Mar10” connection is a stroke of marketing genius that Nintendo officially embraced in recent years. The company began promoting Mario Day around 2016, partnering with retailers, hosting events, and offering discounts on Mario-themed games and merchandise. What started as a fan-driven pun has grown into an annual celebration, giving Nintendo a perfect excuse to shine a spotlight on their flagship character.
How Fans Celebrate Mario Day
Mario Day is all about having fun and paying homage to the Mushroom Kingdom. Here’s how fans and Nintendo typically mark the occasion:
- Gaming Marathons: Dusting off classic consoles or firing up modern titles like Super Mario Odyssey on the Nintendo Switch is a popular way to celebrate. Whether it’s speedrunning Super Mario 64 or exploring Super Mario Galaxy, fans relive their favorite adventures.
- Deals and Discounts: Nintendo often collaborates with retailers to offer special promotions on Mario games, accessories, and merchandise. Keep an eye out for bundles or limited-edition items!
- Cosplay and Creativity: From donning red caps and mustaches to crafting Mario-inspired art, fans get creative. Social media lights up with #MarioDay posts showcasing costumes, cakes, and DIY projects.
- Community Events: Some gaming stores or online communities host tournaments (think Mario Kart races) or trivia nights to test fans’ knowledge of Mario lore.
- Nintendo Announcements: Occasionally, Nintendo uses Mario Day to drop exciting news—think game reveals, updates, or even hints about Mario’s next big adventure.
Mario’s Lasting Legacy
Mario isn’t just a character; he’s a cultural phenomenon.
With over 800 million games sold across the franchise, he’s one of the best-selling video game characters of all time. Beyond gaming, Mario has starred in TV shows, comics, and even a 2023 animated movie, The Super Mario Bros. Movie, which introduced him to a new generation.
His appeal lies in his simplicity and optimism. Mario is an everyman hero—short, stout, and unassuming—who overcomes obstacles with determination and a little help from power-ups. He’s a reminder that anyone can be a hero, whether you’re stomping Goombas or just navigating life’s challenges.
