Zoe Grace Quaid is best known as the daughter of actor Dennis Quaid and the twin sister of Thomas Boone Quaid. Born in 2007, she grew up in a famous Hollywood family but has largely stayed away from the entertainment industry and public attention.
Unlike her older half-brother Jack Quaid, Zoe has not pursued acting. Her story has attracted attention because of her famous family, her serious medical emergency as a newborn, her rare public appearances, and more recent reports about her transition into adulthood.
Here is what is publicly known about Zoe Grace Quaid.

People reports that Zoe and her twin brother were born on November 8, 2007, with Thomas arriving first and Zoe following two minutes later.
Who Is Zoe Grace Quaid?
Zoe Grace Quaid is one of Dennis Quaid’s three children. Her father is a veteran American actor known for films and television projects including The Right Stuff, The Parent Trap, The Day After Tomorrow, and Reagan.
Her mother is Kimberly Buffington, a Texas real-estate professional. Zoe has a twin brother, Thomas Boone Quaid, and an older half-brother, Jack Quaid, from Dennis Quaid’s previous marriage to actress Meg Ryan.
Although she was born into a highly recognizable family, Zoe has maintained a much lower public profile than her father and brother. There is no established record of her pursuing professional acting, and most details about her everyday life have remained private.
That privacy is an important part of understanding why searches for her name continue to generate curiosity.
When Was Zoe Grace Quaid Born?
Zoe Grace Quaid was born on November 8, 2007, in Santa Monica, California.
She was born alongside her fraternal twin brother, Thomas Boone Quaid. According to PEOPLE, Thomas was born first at 8:26 a.m., weighing 6 pounds, 12 ounces, while Zoe arrived two minutes later and weighed 5 pounds, 9 ounces.
The twins were born through a gestational carrier. Their arrival came after Dennis Quaid and Kimberly Buffington had decided to expand their family.
As of 2026, Zoe is 18 years old.
Who Are Zoe Grace Quaid’s Parents?
Zoe’s parents are Dennis Quaid and Kimberly Buffington.
Dennis Quaid has had a long career in Hollywood and has appeared in numerous major film and television productions. Kimberly Buffington, meanwhile, has generally maintained a life away from the entertainment spotlight.
The couple married in 2004 and welcomed their twins three years later. Their marriage eventually ended, with their divorce finalized in 2018.
Dennis later married Laura Savoie in 2020, making Savoie Zoe’s stepmother.
Despite the changes in the family structure, Zoe and Thomas remained an important part of their father’s life.
Zoe Grace Quaid and Her Twin Brother Thomas
Thomas Boone Quaid is Zoe’s twin brother.
The two were born only two minutes apart and experienced one of the most serious events of their childhood together. Their shared beginning has made the twins an important part of Dennis Quaid’s family story.
Like Zoe, Thomas has generally remained outside the entertainment business. The twins have not followed their older half-brother into professional acting.
Recent reporting indicates that the siblings reached another major milestone in 2026 after completing high school. PEOPLE reported that Zoe was set to attend the University of Virginia, while Thomas planned to attend the University of Colorado Boulder. Because these are reported educational plans rather than a detailed public college profile, it is best not to assume more about Zoe’s studies than publicly documented.
Zoe’s Older Half-Brother Jack Quaid
Zoe’s older half-brother is Jack Quaid, the son of Dennis Quaid and Meg Ryan.
Jack was born in 1992 and eventually developed his own successful acting career. He has appeared in projects including The Hunger Games, Scream, Oppenheimer, and The Boys.
This creates an interesting contrast within the Quaid family.
Jack chose a career directly connected to Hollywood, while Zoe has remained largely outside the entertainment industry. Dennis Quaid has publicly expressed pride in all three of his children, while also keeping many details about his younger children’s lives private.
The Serious Medical Emergency Zoe Faced as a Newborn
One of the most significant events associated with Zoe Grace Quaid happened when she was only days old.
In November 2007, Zoe and Thomas were hospitalized at Cedars-Sinai Medical Center in Los Angeles after developing a staph infection. During their treatment, both babies accidentally received an extremely large dose of the blood thinner heparin.
PEOPLE reported that the infants received approximately 1,000 times the recommended dose. The incident placed both newborns in serious danger.
Dennis Quaid and Kimberly Buffington subsequently spoke publicly about the medical error. The event received widespread attention because of the severity of the mistake and because the parents used their experience to raise awareness about patient and medication safety.
Fortunately, Zoe and Thomas survived and recovered. PEOPLE reported that the twins had made a full recovery and were discharged from the hospital in early December 2007.
Did Zoe Grace Quaid Recover From the Heparin Overdose?
Yes.
Zoe and Thomas survived the medication error and recovered from the incident. Their recovery transformed what could have been a devastating family tragedy into an important part of Dennis Quaid’s later advocacy surrounding medical mistakes.
The U.S. congressional record also documents Dennis Quaid’s testimony concerning the twins’ near-fatal heparin overdose and the broader issue of medication safety.
Why Is Zoe Grace Quaid So Private?
Zoe’s public profile is unusual for someone born into a Hollywood family.
Her father is a well-known actor, and her older half-brother has become a prominent actor himself. Yet Zoe has not established a comparable entertainment career.
Publicly available information about her childhood is relatively limited. Dennis Quaid has occasionally discussed his children, but he has generally avoided turning his younger children’s private lives into ongoing celebrity coverage. PEOPLE specifically notes that Quaid remains fairly private about Thomas and Zoe.
This means many claims about Zoe’s hobbies, personality, relationships, or daily life should be treated carefully unless they come from a reliable source or from Zoe herself.
Zoe Grace Quaid’s Public Appearances
Although Zoe has largely stayed out of the spotlight, she has occasionally appeared alongside her father.
One notable appearance came in August 2024, when Zoe accompanied Dennis Quaid to the Los Angeles premiere of Reagan. Photographs from the event showed father and daughter together at the Hollywood premiere.
The appearance attracted attention precisely because Zoe is rarely seen at major entertainment events.
It also demonstrated that although she has chosen a private life, she sometimes supports her father at important professional occasions.
What Is Zoe Grace Quaid Doing in 2026?
As of 2026, Zoe Grace Quaid is entering adulthood.
PEOPLE reported that she had graduated from high school and was set to attend the University of Virginia, while her twin brother was expected to attend the University of Colorado Boulder.
Beyond those educational plans, very little has been publicly confirmed about her future career.
That distinction matters. There are numerous online articles making claims about Zoe’s career interests, hobbies, social-media activity, and personal life, but not all of those claims are supported by strong primary sources.
For now, the safest conclusion is that Zoe is building her own life away from Hollywood and has not publicly announced an entertainment career.
Does Zoe Grace Quaid Act in Movies or TV Shows?
No publicly documented acting career has been established for Zoe Grace Quaid.
Unlike her father Dennis and half-brother Jack, Zoe has not appeared as a professional actor in the major film and television projects associated with the Quaid family.
Her connection to Hollywood comes primarily through her family rather than through her own professional work.
Does Zoe Grace Quaid Have Social Media?
There is no widely verified public social-media profile that establishes Zoe Grace Quaid as an active public personality.
Because Zoe has deliberately maintained a private life, readers should be cautious with accounts using her name. A profile claiming to belong to a celebrity’s private family member is not necessarily authentic simply because it uses the correct name.
For the same reason, unverified posts should not be treated as evidence about her relationships, education, or personal activities.
Zoe Grace Quaid’s Height and Personal Details
Zoe’s exact height has not been reliably confirmed through an authoritative public source.
The same applies to many personal details that appear on celebrity-biography websites. When a person maintains a private life, estimates based on photographs or unsourced online profiles should not be presented as established facts.
There is also no reliable public basis for assigning Zoe a specific career, relationship status, or personal net worth.
Keeping those distinctions clear makes a biography more accurate and avoids turning speculation into fact.
