How old is Claire Holt?

What is Claire Holt’s birth date?

Claire Rhiannon Holt was born on in Brisbane, Queensland, Australia (Encyclopaedia Britannica). Her full name, including her middle name, is confirmed by biographical records (Wikipedia).

How old is Claire Holt now?

As of today, Claire Holt is 37 years old. Multiple celebrity age trackers, including Famous Birthdays and Cameo, list her current age consistently.

The upshot

Claire Holt’s birth date is rock‑solid across authoritative sources — there is no dispute over her year or day of birth, which is rare for celebrities who started young.

The pattern: Holt’s age at birth is a fixed point — June 11, 1988 — and all career milestones are calculated from that date. The implication: her age timeline is unusually clean for a child star.

How old was Claire Holt in H2O?

How old was Claire Holt in season 1 of H2O?

H2O: Just Add Water premiered in 2006 (Wikipedia – H2O: Just Add Water). Claire Holt was born in June 1988, so when filming began in 2005, she had just turned 17. She portrayed the character Emma Gilbert in seasons one and two (H2O Just Add Water Wiki).

How old was Claire Holt when filming H2O?

Across the show’s run (2006–2008), Holt aged from 17 to 19. This meant she played a teenager for all three seasons, with her real‑life age closely mirroring her character’s high‑school years (Famous Birthdays).

Why this matters

Holt was cast at 17 — the same age as her character — which gave the show an authentic teen energy that adult actors playing teenagers often struggle to replicate.

The implication: Holt’s teenage years are permanently documented on screen, making her age during H2O one of the most verifiable career milestones in young Hollywood.

How old was Claire Holt in The Vampire Diaries?

When did Claire Holt join The Vampire Diaries?

She first appeared as Rebekah Mikaelson in Season 3 of The Vampire Diaries, which aired in 2011 (The Vampire Diaries Wiki). In 2011, Holt was 23 years old.

She portrayed Rebekah Mikaelson, an ancient vampire from the Original family. She continued the role in The Originals spin‑off from 2013 (Wikipedia). During the period she recurred on The Vampire Diaries (2011–2013), she was between 23 and 25 years old.

The paradox

Holt played a 1,000‑year‑old vampire at age 23 — a reminder that in supernatural TV, an actor’s real age often has little to do with the character’s.

The catch: this age gap between actor and character is the widest of her career — a 23-year-old playing a millennium-old being.

What is Claire Holt’s real name?

Is Claire Holt her birth name?

Yes — Claire Rhiannon Holt is her legal name (Wikipedia). There is no stage‑name alteration; she has used her birth name throughout her career.
