He’s 70.
Honestly, that’s the short answer. If you’re looking for the quick math on how old is pope leo 2025, Robert Francis Prevost—now known to the world as Pope Leo XIV—hits that milestone age this year. Born on September 14, 1955, in Chicago, he’s basically the face of a new generation at the Vatican.
It feels weird saying a 70-year-old is the "young" guy in the room, but in the world of the papacy, it kind of is. His predecessor, Pope Francis, was well into his 80s when he passed away in April 2025. Moving from an 88-year-old pontiff to a 69-year-old (at the time of election) was a jolt of energy the Church hasn't felt in a while.
How Old Is Pope Leo 2025 Compared to History?
People usually expect popes to be, well, ancient. We’ve grown used to seeing the "grandfather of the world" figure. But Leo XIV is different. When he stepped onto that balcony on May 8, 2025, he wasn't just the first American; he was a man who still has a lot of miles left on the clock.
Think about it. Pope Leo XIII, the guy he actually named himself after, lived to be 93. If Leo XIV follows that path, we’re looking at a 20-plus year papacy. That’s a massive amount of time to change things. He’s a Baby Boomer. He’s the first pope born after World War II. He grew up with NASA, the Beatles, and the Cold War. That matters. It changes how he sees the world compared to someone born in the 1930s.

Why 70 Is the New 50 in the Vatican
You’ve probably seen the videos of him. He’s athletic. He’s been caught on camera catching baseballs thrown his way in St. Peter’s Square with the reflexes of a guy who actually grew up playing the game.
He’s not just sitting in a library. He’s at the papal villa in Castel Gandolfo, swimming laps and playing tennis. It’s a bit of a departure. While Francis turned the villa into a museum, Leo XIV has reclaimed it as a place to stay fit and clear his head. This physical stamina is a big deal because the job is grueling.
A Quick Timeline of His Life

The math is simple: how old is pope leo 2025? He turns 70 this September.
The Chicago Connection
It’s still surreal to many that the Pope is from Illinois. He’s a dual citizen of the U.S. and Peru. That dual identity is probably why he’s so popular right now. He speaks English with that distinct Midwestern clarity and shifts into perfect Spanish for the crowds from Latin America.

He isn't some distant royal. He’s a guy who knows what a Chicago winter feels like. He’s a guy who studied math. That analytical background shows up in how he handles the Vatican’s messy finances. He doesn’t just pray over the books; he actually understands the spreadsheets.
What Most People Get Wrong About His Age
Some critics said he was too young. They worried he didn't have the "gravitas" of an older man. But that's mostly noise. Most Catholics were actually relieved. They wanted someone who could travel without a medical team in every suitcase.
In his first major trip to Turkey and Lebanon late in 2025, he was on his feet for hours. He didn't look tired. He looked like a man who was just getting started. He’s using his 70th year to set a pace that most world leaders half his age would struggle to keep up with.
Why the Name Leo Matters
He didn't pick "Francis II" or "John Paul III." He went back to "Leo."

The last Leo (XIII) was a giant. He wrote the famous Rerum Novarum, which basically invented the Church’s modern stance on workers' rights. By taking that name at age 69, our current Pope was signaling that he’s here to do work. He’s here for the social issues.
He is leaning into the legacy of "Leo the Great" as well. That’s the guy who supposedly talked Attila the Hun out of sacking Rome. It’s a bold choice. It says "I’m here to lead, not just occupy the chair."
Looking Ahead to 2026 and Beyond
As 2025 wraps up, the focus is shifting from his age to his actions. He’s navigated the "Cupich-Durbin episode" and hosted a massive Jubilee of Youth that saw over a million kids screaming for him like he was a rock star.
His age is his greatest asset right now. He’s old enough to have wisdom but young enough to actually execute a long-term vision. He isn't rushing because he doesn't feel like he’s running out of time.
If you want to keep up with his papacy, start by looking at his recent appointments. He isn't picking ideologues. He’s picking "middle of the road" pragmatists. He’s building a team that looks a lot like him—deliberate, calm, and focused on the job.
Check the Vatican’s official calendar for his upcoming 2026 trips. Watching how he handles the travel schedule is the best way to see his "70 years young" energy in action. Keep an eye on his Wednesday audiences too; they’re where his personality really comes out.
