So you’re wondering how old John Lennon’s son is, right? It’s one of those questions that pops up because the Beatles feel both ancient and timeless. Well, the short answer is that John Lennon had two sons, and they’re at very different life stages.
Meet Sean Ono Lennon
The most famous answer is Sean Ono Lennon, John’s son with Yoko Ono. Born on October 9, 1975, Sean turned 49 in 2024. Yes, that means John’s youngest kid is now nearly 50—wild, right?
Sean is exactly the same age his father was when the Beatles broke up in 1970. Imagine that: at 49, John was already a solo artist, a peace activist, and five years away from being killed. But Sean? He’s just a chill musician and producer, still making art without the same crushing weight.

What about Julian Lennon?
John’s other son, Julian Lennon, is from his first marriage to Cynthia Powell. Born on April 8, 1963, Julian is now 61. That’s older than his dad ever got to be—John died at 40.
Julian was the inspiration for songs like Hey Jude, but he and John had a rocky relationship. Now in his sixties, Julian has his own band, writes books, and even does photography. It’s a little bittersweet, isn’t it? The boy who inspired a lullaby is now older than the man who sang it.

Why does this matter?
Because it’s a weird time-travel trick. John Lennon has been gone for over 40 years, but his kids are still here, aging in real time. Sean is now the age when his dad made Double Fantasy. Julian is older than John ever was. It makes you wonder: what would John think of his sons as middle-aged men?
Here’s a fun comparison: When Sean was born, the Rolling Stones were still in their twenties. Now Sean is nearly 50, and Mick Jagger is 80. Time flies—and it doesn’t care about rock star legacies.

The cool part
Both brothers are doing their own thing, not just living in John’s shadow. Sean collaborates with artists like Cibo Matto and Mystical Weapons. Julian focuses on his acoustic rock and charity work. They’ve both said they’re okay with not being “the next John Lennon.”
So, how old is John Lennon’s son? It’s two answers: 49 and 61. But really, the question is less about age and more about legacy. They’re living proof that even after a legend fades, the story keeps going—one birthday at a time.

A chill thought
Next time you hear Imagine, remember: Sean was just a toddler when his dad wrote that. Now Sean is nearly 50, and the song still sounds fresh. That’s the kind of weird math only rock and roll can do.
So go ahead, look up Sean’s latest album or Julian’s photography. They’re not trying to be John—they’re just being themselves. And honestly? That’s way cooler than being a carbon copy.
