Zac Efron may be known for headlining blockbuster hits like The Greatest Showman and High School Musical, but off-screen he plays another role just as wholeheartedly: devoted big brother. Born in October 1987 to David Efron and Starla Baskett, Zac became a sibling about four and a half years later when his younger brother, Dylan, arrived in February 1992. After their parents divorced in 2016, David remarried and welcomed two more children, Olivia and Henry, expanding the Efron crew even further.
Zac often gushes about his siblings in interviews and shares sweet family moments on Instagram, making it clear how much they mean to him. But who exactly are the other Efron kids, and what are they up to? Let’s take a closer look…

Dylan Efron (33)
Dylan Efron was born on the February 6, 1992, making him roughly four and a half years younger than Zac – and it’s clear the two have a strong bond. As well as sharing heartwarming snaps with his family on his Instagram page, Dylan also followed in his big brother’s footsteps, joining the film industry as a production coordinator on films like Ready Player One and American Sniper.
The Efron brothers have also frequently collaborated on exciting projects; Dylan served as a producer on Zac’s Emmy Award-winning Netflix documentary series, Down to Earth with Zac Efron (2020), and previously joined his brother in their YouTube series Off the Grid (2019), where the duo explored the great outdoors without electronic devices.

Earlier in the season, Dylan performed an emotional tribute dance to Olivia. “I wasn’t expecting to be a big brother, but immediately I was inseparable from her,” Dylan shared in a teary introduction video to his number, set to Zac and Zendaya’s ballad “Rewrite the Stars” from The Greatest Showman.
“Now, being able to dance to ‘Rewrite the Stars,’ this is a nod to my brother. Zac’s always taken care of me and he did things that were so selfless. I wanna be that to Olivia.”

Olivia Efron (5)
Born on Christmas day in 2019, Olivia is the first child of David Efron and his current wife, Jenny. Though there’s a sizable, 28-year age difference between Olivia and her next oldest brother, it’s clear this age gap hasn’t stopped the siblings from becoming super close.
Zac’s fans will have spotted his adorable sister on his Instagram page frequently, with the High School Musical star sharing this sweet picture of him reading a book to Olivia, affectionately calling her “my Valentine” in the caption.
He also shared a charming video of him and Dylan playing in the waves with their little sister at the beach, with commenters loving the tender moment. “She’s absolutely precious – savour this time,” one fan wrote.

It’s clear Olivia has also inherited the family’s showbiz talent; fans couldn’t believe how amazing the 5-year-old was during Dylan’s dedication night routine on Dancing With the Stars, where she briefly joined her big brother on stage looking every inch the budding ballerina. “She pointed her toe and straightened her leg on that first lift like rent was due,” one commenter remarked, and many fans of the show labeled the routine their favorite of the night.

Henry Efron
Though it’s not known exactly when Henry was born, he arrived sometime after his sister, Olivia — and it’s clear his older siblings adore spending time with him.
In a touching birthday tribute to Zac, Dylan shared a hilarious picture of the quartet, affectionately captioning it, “I know exactly the type of big brother I want to be for Olivia and Henry because you were that brother to me.”
The siblings are clearly no strangers to pulling a brotherly prank on Henry as well. Dylan took Olivia and Henry to a theme park for Henry’s birthday, promising his siblings that the front row of a ride they were going on wouldn’t get splashed with water… “Big brother energy,” Dylan jokingly captioned the TikTok, featuring a less-than-amused Henry, who’d gotten drenched.
