If you’ve ever watched a Rafael Nadal match, you’ve seen her. Sitting in the player’s box, usually right next to Rafa’s wife, Mery "Xisca" Perelló, and his mother, Ana Maria Parera. She is the one with the intense eyes, the one who looks like she’s playing every point from the bleachers. That is Maribel Nadal.
Most people just see her as "the sister." But honestly, if you talk to anyone in the Manacor inner circle, they’ll tell you she is way more than that. She is the anchor.
Rafael Nadal and His Sister: A Bond That Defies the "Annoying Sibling" Trope
Growing up, siblings usually fight. They bicker over the remote or who gets the last piece of ensaimada. But Rafa and Maribel? Different story. In his memoir, Rafa: My Story, the tennis legend basically admits that Maribel is one of the most important women in his life.
He didn't treat her like an annoying younger sister. Actually, he used to beg her to hang out with him and his friends. That’s kinda rare, right? They are only two years apart—Rafa was born in 1986, Maribel in 1988—and that small gap made them more like best friends than rivals.
She was the one who introduced him to Mery. Think about that for a second. Without Maribel, the most stable relationship in sports history might not even exist. She went to school with Mery in Mallorca, and the rest is history.
What does Maribel Nadal actually do?
She isn't just a professional cheerleader. Maribel is a powerhouse in the family business. She serves as the Marketing and Commercial Director (and Deputy General Manager) of the Rafa Nadal Academy in Manacor.

She isn't just a "face" for the brand. People who work there say she’s the "operational brain." She manages the gym, the international school, the residence, and the beauty center. Oh, and she’s a beast on the court herself.
She plays padel. She plays tennis. She plays golf. Basically, if it involves a ball and a score, she’s probably better at it than most people you know. In 2021, she even made her debut in an ITF Masters event (the 30+ category) playing mixed doubles with Carlos Moyá. Yeah, that Carlos Moyá.
The launch of Crabs Company
Beyond the academy, Maribel is a fashion entrepreneur. She launched Crabs Company, a men’s clothing brand inspired by the Mediterranean lifestyle of Mallorca.
It’s very on-brand for the family—discreet, quality-focused, and deeply rooted in their island home. She’s often seen wearing the brand’s gear, bridging that gap between the sports world and the fashion industry without making it feel like a forced "influencer" cash grab.
The Dark Side of the Spotlight: The 2025 Stalking Incident
Being the sister of a global icon isn't always easy. In late 2025, the family dealt with a terrifying situation that finally hit the courts in September of that year.

A man named Sebastian Moll McCarthy was convicted of stalking Maribel. This wasn't just a few weird DMs. He made repeated trips to the academy in Mallorca, flooded her phone with "incessant" calls, and even sent messages saying he "wanted to taste her blood."
It was a nightmare.
Maribel had to hire a bodyguard. Her mental health took a massive hit. Imagine trying to run a multi-million dollar academy while wondering if the guy in the lobby is there to hurt you. Fortunately, the Spanish court handed down a suspended jail sentence and a strict two-year restraining order. It was a rare, public glimpse into the security pressures the Nadal family deals with daily.
Why she is the "Grounded" Force
Rafa is famously ritualistic. The water bottles must face a certain way. The socks must be at a specific height. The world of professional tennis is a bubble of high-stakes anxiety.
Maribel is the one who pops that bubble.
