If you grew up anywhere near a television between 2005 and 2010, the "JoBro" mania was probably inescapable. But even if you’ve been a fan since the curly-hair Nick era, people still find themselves double-checking the basics. What are the Jonas Brothers names, exactly? And why does everyone keep talking about a "Bonus Jonas" who isn't actually in the band?
Honestly, the family tree is a bit more than just a trio. While the world knows the Jonas Brothers as the pop-rock powerhouse behind hits like "Sucker" and "Burnin' Up," there are actually four brothers in total.
The Official Lineup: Kevin, Joe, and Nick
The core band consists of three brothers. They were raised in Wyckoff, New Jersey, and got their start when the youngest of the trio, Nick, was discovered in a hair salon. It's a classic showbiz origin story that sounds fake, but it's 100% real.
Kevin Jonas (Paul Kevin Jonas II)
The eldest. Born November 5, 1987.
Kevin is basically the backbone of the group’s live sound, usually found with a guitar strapped to his chest. While he doesn't take as many lead vocals as his younger siblings, he’s often the one handling the business side of things. In 2025, he even surprised fans by dropping a debut solo single called "Changing," proving he’s got more than just rhythm guitar skills. He’s also the first one to settle down, having married Danielle Deleasa back in 2009.
Joe Jonas (Joseph Adam Jonas)
The middle child (of the band, at least). Born August 15, 1989.
Joe is the high-energy frontman with the expressive eyebrows. You might remember his side project, DNCE, and that "Cake by the Ocean" song that lived in everyone's head rent-free for three years. In the band, he shares lead vocal duties with Nick. Lately, Joe has been making waves not just in music but on the screen, recently wrapping a 20th-anniversary tour that ended with a massive New Year's Eve bash in Miami to ring in 2026.

Nick Jonas (Nicholas Jerry Jonas)
The youngest member of the group. Born September 16, 1992.
Nick was the original "star" who got the brothers signed to Columbia Records. He's a multi-instrumentalist who plays piano, guitar, and drums. Nick has had a massive solo career—think "Jealous"—and has been very open about his life with Type 1 diabetes. Right now, he’s kicking off 2026 with a brand new solo record called "Sunday Best," featuring the single "Gut Punch."
Wait, Who is the Fourth Brother?
If you’ve heard the term "Bonus Jonas," you’re thinking of Frankie Jonas.
His full name is Franklin Nathaniel Jonas, and he was born in 2000.
Frankie was never an official member of the Jonas Brothers band. He was just a kid when his brothers became global superstars, though he did pop up in their Disney Channel shows and even voiced a character in the movie Ponyo.
For a long time, he was the "little brother" everyone recognized but didn't see on stage. That changed recently. Frankie has stepped into his own spotlight, co-hosting the reality competition show Claim to Fame with his big brother Kevin. He’s also a musician in his own right, though his vibe is much more "indie/alternative" than the pop-rock sound his brothers are known for.

The Family Business in 2026
The brothers aren't just kids with flat-ironed hair anymore. They’ve evolved into what many critics call "legacy acts," though they’re still topping charts.
In late 2025, they released a project called "Greetings from Your Hometown," which served as a massive 20th-anniversary celebration of their career. They even did a holiday movie, A Very Jonas Christmas Movie, because at this point, they’ve leaned fully into the family-man brand.
Fun Fact: Nick was almost a solo artist named "Nicholas Jonas" before the label realized the brothers had a better "garage-rock" chemistry as a trio.

- Kevin: The oldest, plays lead guitar, married to Danielle.
- Joe: The middle, lead singer, former frontman of DNCE.
- Nick: The youngest in the band, lead singer/multi-instrumentalist, married to Priyanka Chopra.
- Frankie: The "Bonus Jonas," not in the band, TikTok star, and TV host.
It’s worth noting that their father, Kevin Jonas Sr., and mother, Denise, were both singers too. Music is literally in their DNA. While they had a rough breakup back in 2013—which they now joke about constantly—their 2019 reunion with "Sucker" proved that the "Jonas" brand is bigger than the sum of its parts.
If you want to keep up with them today, look for Nick’s new solo album Sunday Best dropping this February, or catch Kevin and Frankie on the latest season of Claim to Fame. They might be older, but they aren't slowing down.
To dive deeper into their discography, your best bet is to start with their 2023 release, The Album, which captures their modern "yacht rock" sound perfectly before moving into their 2025 anniversary tracks.
