The white smoke from the Sistine Chapel on May 8, 2025, didn’t just signal a new leader; it signaled a massive shift in the Catholic Church’s geography. For the first time ever, a Chicago-born American, Cardinal Robert Francis Prevost, stepped onto the balcony as Pope Leo XIV.
He’s not exactly the "young" pope people were expecting if they spent too much time watching HBO, but he’s a far cry from the frail image often associated with the papacy in its later years.
So, how old is the new Pope Leo XIV?
Right now, as we navigate the start of 2026, Pope Leo XIV is 70 years old.
He hit that milestone birthday on September 14, 2025. Honestly, in the world of the Vatican, 70 is practically middle-aged. Compare that to Pope Francis, who was 76 when elected, or Benedict XVI, who was 78. Leo XIV—or "Father Bob" as some of his old Augustinian buddies in Chicago still call him—brings a different kind of energy to the Apostolic Palace. He’s a mathematician by training, a canon lawyer by trade, and a missionary by heart.
You’ve probably seen the headlines. People are obsessed with his age because they want to know how long this "American era" will last. If he lives as long as his predecessor, we’re looking at nearly two decades of a Leo papacy. That’s enough time to fundamentally rewire the Church.
Why 70 is the "Goldilocks" Age for a Pope
There’s a reason the Cardinals went with someone in their late 60s (at the time of the Conclave). If you pick someone too young, say a 55-year-old, you risk a 30-year reign that could turn into a stagnant monarchy. Pick someone 80, and you’re just looking for a "caretaker" who won't change much.
Leo XIV is in that sweet spot.
- He’s old enough to have a deep resume. He led the worldwide Augustinian order for over a decade. He spent years in the trenches in Peru. He knows how the Vatican's bureaucracy—the Curia—works because he headed the Dicastery for Bishops.
- He’s young enough to travel. We’re already hearing rumors about a massive trip back to his home turf in the United States and a visit to Algeria in 2026.
- The "Leo Effect" is real. There's a noticeable pep in the Vatican's step lately. Whether it's his new, more modern pastoral staff unveiled on Epiphany 2026 or his focus on AI ethics, he isn't acting like a man ready for retirement.
What Really Happened with the Name "Leo"?
Choosing a name is the first real act of a new Pope. It's a brand statement. By choosing Leo XIV, he bypassed names like "Francis II" or "John Paul III."
The last Pope Leo (Leo XIII) died in 1903. He was the guy who wrote Rerum Novarum, the document that basically invented modern Catholic social teaching on labor rights and the poor. By taking this name at age 70, the new Pope is signaling a return to "Intellectual Catholicism." He wants to bridge the gap between ancient tradition and the terrifyingly fast world of 2026.
The First "Digital Native" Pope?
Okay, maybe not "native," but he's close. Since he studied mathematics at Villanova (Class of '77), he actually understands the logic behind the algorithms he's now critiquing.
In his recent speeches, he’s been surprisingly tech-literate. While most 70-year-olds are struggling with their TV remotes, Leo XIV is preparing a major teaching document on artificial intelligence. He’s worried about what happens to the human soul when machines start doing the thinking. It’s a weird, fascinating pivot for the Church.
What’s Next for Leo XIV in 2026?
The "honeymoon phase" of the Jubilee Year is officially over. Now that the Holy Door has been closed, the real work starts.
He just finished a massive meeting—an extraordinary consistory—with the world's Cardinals in early January. He didn't just give them a pep talk; he gave them a roadmap. He's looking at restructuring how the Vatican spends its money and how it treats its staff.

Watch these three things in the coming months:
- The US Visit: With 2026 being the 250th anniversary of the United States, expect a homecoming that will probably shut down half of Chicago and D.C.
- The AI Encyclical: This could be the most important document of his papacy, setting the moral guardrails for tech companies globally.
- New Leadership: Now that he's settled in, watch for him to replace older Vatican officials with younger, more global voices from Africa and Asia.
If you’re tracking the "new Pope Leo," don't just look at his age on a calendar. Look at the schedule he’s keeping. He’s 70, but he’s moving like he’s 50. For a Church that often moves at a glacial pace, this American Pope seems to be in a bit of a hurry.
