If you still think Miley Cyrus was born "Miley," you’re actually in the majority, but you're also wrong. Honestly, the story of her name is kind of a wild ride through 90s optimism, a massive Disney-fueled rebrand, and a tribute to a grandfather most fans have never even heard of.
She wasn't born a Miley. Not even close.
When Billy Ray Cyrus and Tish Cyrus welcomed their daughter in November 1992, they didn't reach for a trendy baby name book. They went for something that sounded more like a prophecy. They named her Destiny Hope Cyrus. Billy Ray has been pretty open about why: he genuinely believed it was her destiny to bring hope to the world. No pressure for a newborn, right?
But "Destiny Hope" didn't even last through her infancy before a nickname took over and changed everything.
The "Smiley" to "Miley" Pipeline
It's one of those classic family stories that sounds like a PR myth but is actually true. As a baby, she was apparently so relentlessly cheerful that her parents started calling her "Smiley."
Eventually, as anyone with a nickname knows, it got shortened. The "S" dropped off. "Smiley" became "Miley." By the time she was old enough to walk and talk, basically nobody in her inner circle was calling her Destiny. She was Miley to her parents, Miley to her siblings, and eventually, Miley to the casting directors in Hollywood.
By the time Hannah Montana premiered in 2006, the world knew her as Miley Cyrus. But legally? On her passport and birth certificate, she was still Destiny Hope.
That created a bit of a weird disconnect. You've got the biggest teen star on the planet—a girl whose face is on every lunchbox and t-shirt in America—and her legal documents don't match her brand.
Making it Legal: The 2008 Court Filing
In early 2008, when she was 15 years old, Miley (with her parents' help, since she was a minor) headed to the Los Angeles Superior Court. The goal was simple: kill off "Destiny Hope" and make "Miley" official.
The court documents filed at the time were pretty straightforward. They stated that she had been "commonly known as Miley Cyrus since she was a young child" and they wanted her legal identity to reflect her real life. On May 1, 2008, a judge signed off on it.

Destiny Hope Cyrus was officially gone.
But she didn't just change her first name. She also ditched her middle name. "Hope" was swapped out for Ray. Most people assume this was just a nod to her dad, Billy Ray Cyrus. While that's partly true, it was actually a deeper tribute to her grandfather, Ronald Ray Cyrus.
He was a Democratic politician from Kentucky who she was incredibly close to. He passed away in 2006, right as her fame was exploding. Changing her middle name to Ray was her way of keeping his memory attached to her identity as she became a global icon.
The Hemsworth Era: A Temporary Shift
If you think the 2008 change was the end of the story, you've forgotten about the Liam Hemsworth years.

When Miley married Liam in December 2018, she did something surprisingly traditional. She took his last name. Liam actually revealed this on Live with Kelly and Ryan in early 2019, saying her legal name had become Miley Ray Hemsworth.
She didn't use it professionally—she was still Miley Cyrus on album covers—but on her Social Security card and marriage license, the "Cyrus" was temporarily shelved.
Of course, the marriage didn't last. They split in 2019, and the divorce was finalized in 2020. While she hasn't made a big public spectacle of the paperwork, she reverted to being Miley Cyrus legally and professionally.
Why the Name Still Matters Today
It's funny how a name can define an era. In 2024, during her interview with David Letterman on My Next Guest Needs No Introduction, Miley looked back at her birth name with a mix of affection and "cringe."
She told Letterman that while "Destiny Hope" was a "big shoe to fill," she appreciated the intention her parents had. It set a certain energy for her life. But she also joked about how much she disliked it as a kid, making a "sick" gesture when talking about the formal name.
The name change was more than just a legal formality. It was the first time Miley took control of her own narrative. By ditching the "Destiny" her parents chose and cementing the "Miley" she had become, she signaled that she was the one in charge of her identity.

Actionable Insights for Fans and Researchers
If you're looking for her official records or trying to verify her history for a project, keep these things in mind.
- Check the Date: If you see a document from 2006 or 2007, it will likely list her as Destiny Hope Cyrus. Anything post-May 2008 should be Miley Ray Cyrus.
- The "Ray" Nuance: Don't just credit Billy Ray. If you're writing about her history, mentioning Ronald Ray Cyrus shows you actually know the deeper family lore.
- Professional vs. Legal: Remember that many celebrities use a "stage name" that differs from their legal one. Miley is rare because she actually went to court to make them identical, which helped simplify her massive business empire (contracts, royalties, and touring documents).
Whether you call her Miley, Destiny, or even Hannah, the name is a reflection of a career built on constant evolution. She’s never been one to stay in one box for long.
