Dylan O’Brien has been a familiar face to television and movie audiences for more than a decade. From his breakout role as Stiles Stilinski in Teen Wolf to his work in The Maze Runner, Love and Monsters, Ponyboi, and Twinless, the actor has built a career around memorable characters and a deliberately private personal life.
That privacy is one reason fans remain interested in his relationships. The question of Dylan O’Brien girlfriend has appeared frequently online, especially since the actor was linked to model Rachael Lange.
As of 2026, O’Brien and Lange continue to be publicly linked. They have been seen together on several occasions, including a 2026 Independent Spirit Awards appearance and a New York City outing with their dog in June 2026. Their relationship remains relatively low-key, with neither celebrity regularly sharing details about their private life.
This article looks at O’Brien’s current relationship, his dating history, and the difference between confirmed relationships and celebrity rumors.

Who Is Dylan O’Brien?
Dylan Rhodes O’Brien is an American actor who was born on August 26, 1991, in New York City. He became widely known after playing Stiles Stilinski on MTV’s Teen Wolf, a role that helped establish him as one of the most recognizable young actors of his generation.
His popularity increased further when he played Thomas in The Maze Runner film series. The movies turned him into a major young-adult movie star and gave him opportunities to take on more varied roles.
O’Brien has since moved between mainstream films, independent projects, television, and music-related work. He appeared in Taylor Swift’s All Too Well: The Short Film and later received attention for films including Ponyboi and Twinless.
Despite being a well-known actor, he has generally avoided making his private life the center of his public image.

Is Dylan O’Brien Dating Anyone in 2026?
Yes. Based on recent public appearances, Dylan O’Brien is currently linked to model Rachael Lange.
The pair first attracted widespread attention in early 2023, when they were photographed holding hands during Paris Fashion Week. Since then, they have appeared together at different times while generally keeping their relationship away from the spotlight.
In June 2026, the couple was photographed walking together in New York City with their dog. That recent appearance provides the clearest current public evidence that they remain together.
It is worth separating public evidence from online speculation. O’Brien and Lange have not turned their relationship into a constant social-media feature, so many details reported online are based on photographs or observations rather than lengthy statements from the couple themselves.
For that reason, it is more accurate to say they are publicly linked and appear to be together rather than make assumptions about private aspects of their relationship.
Who Is Rachael Lange?
Rachael Lange is a model and photographer who has become known to entertainment audiences largely through her relationship with O’Brien.
Unlike many celebrity couples, Lange and O’Brien have not built their public image around frequent joint interviews or highly publicized romantic moments. Their appearances together have mostly come through photographs taken at fashion, entertainment, or everyday events.
Lange has her own career and public presence, while O’Brien continues to focus heavily on acting.
Their relatively independent professional lives may be one reason the relationship has attracted interest without becoming an aggressive media spectacle.
When Did Dylan O’Brien and Rachael Lange Start Dating?
The exact beginning of their relationship has not been publicly documented in a detailed way.
Reports generally trace their public connection to late 2022 or early 2023. They were photographed holding hands in Paris in January 2023, which sparked widespread dating reports. Later coverage continued to connect the two.
By 2023, the relationship appeared increasingly established. Lange later shared photographs that fans interpreted as a more direct acknowledgment of the couple.
Because the pair has remained private, it is difficult to establish a precise “official” dating anniversary. A responsible account should therefore avoid presenting an exact start date as confirmed fact.
Their First Public Appearance
The Paris Fashion Week appearance became an important moment in the couple’s public timeline.
O’Brien and Lange were photographed together while holding hands, giving fans the first strong visual indication that their connection was romantic rather than simply friendly.
The images quickly circulated through entertainment media. Unlike some celebrity relationships that begin with an official announcement, this one developed through public sightings.
That pattern has continued. Instead of regularly discussing their relationship in interviews, O’Brien and Lange have mostly allowed occasional photographs to speak for themselves.
Dylan O’Brien and Rachael Lange in 2025
The couple continued to be linked throughout 2025.
Entertainment reports noted that they remained together while maintaining a low profile. They were also photographed together at the 2025 Sundance Film Festival, further supporting reports that the relationship had continued well beyond its initial public appearance.
By this point, the relationship had lasted long enough to move beyond a brief celebrity rumor. Multiple public sightings over several years make the connection considerably better supported than some of the short-lived rumors associated with O’Brien earlier in his career.
Still, neither O’Brien nor Lange has made their private life a major promotional subject. That distinction matters when comparing their relationship with the actor’s earlier rumored connections.
Their 2026 Public Appearance
In June 2026, O’Brien and Lange were spotted together during a walk in New York City. The pair were accompanied by their dog and appeared to be enjoying an ordinary afternoon rather than attending a major entertainment event.
Earlier in 2026, they also attended the Independent Spirit Awards together. Their joint appearance at the ceremony was another public indication that they were still together.
For fans searching for the latest information about Dylan O’Brien girlfriend, these 2026 sightings are particularly relevant because they are more recent than older dating reports.
The important takeaway is simple: O’Brien does not appear to be single based on the latest publicly available evidence. He continues to be linked to Rachael Lange.
Why Do They Keep Their Relationship Private?
Privacy has been a recurring feature of O’Brien’s personal life.
Even during his long relationship with actress Britt Robertson, he rarely made the relationship a major part of his public persona. He occasionally discussed everyday activities, but he generally avoided turning his romance into entertainment content.
That approach seems to have continued with Lange.
There is also a practical reason for celebrity privacy. O’Brien became famous at a relatively young age, and the intense attention surrounding Teen Wolf and The Maze Runner meant that his personal life was often discussed alongside his career.
Keeping relationships private can give actors more control over what becomes public.
Dylan O’Brien and Britt Robertson
Britt Robertson is the most clearly documented long-term relationship in O’Brien’s dating history.
The two met while working on the 2012 romantic comedy The First Time. Their professional connection developed into a real relationship, and they remained together for several years.
O’Brien occasionally spoke warmly about Robertson during the relationship. In a 2017 interview, he described staying at home with her, their dogs, and watching Bachelor in Paradise as one of their favorite date-night activities.
The relationship ended in 2018. Us Weekly later confirmed their split in December of that year.
Because it lasted for years and was acknowledged publicly, the Robertson relationship is very different from several of the rumors that followed.
The Chloë Grace Moretz Rumors
Chloë Grace Moretz and Dylan O’Brien were linked in entertainment reports in 2018.
The connection attracted extra attention because O’Brien had publicly mentioned Moretz years earlier as a celebrity crush. However, the circumstances were more complicated than some headlines suggested.
In 2018, the two were reportedly seen spending time together in Los Angeles. Reports described them as friendly and somewhat affectionate, but neither actor publicly confirmed that they were in a serious relationship.
Therefore, Moretz should be described as a rumored romantic connection rather than a confirmed girlfriend.
Moretz later married model and photographer Kate Harrison in 2025, making it especially important not to present the old O’Brien rumors as an ongoing relationship.
Other Dating Rumors
O’Brien has been connected to several other names in celebrity coverage, including Sarah Ramos, Chloe Bennet, Sabrina Carpenter, and singer Gracie Abrams.
These stories vary significantly in reliability.
For example, the Ramos rumors gained attention after she and O’Brien recreated a scene from The Social Network. That alone was not confirmation of a romantic relationship.
Similarly, O’Brien and Abrams were linked after being seen together, but neither publicly confirmed that they were dating. Harper’s Bazaar also described the connection as unconfirmed.
Sabrina Carpenter was another name associated with O’Brien in 2022, but reports about their connection did not develop into a confirmed long-term relationship.
This is why a dating-history article should distinguish between a confirmed relationship, a public sighting, and an internet rumor.
Dylan O’Brien’s Career and Personal Life
O’Brien’s career has changed considerably since Teen Wolf.
His performance as Stiles made him a fan favorite, while The Maze Runner established his ability to lead a major film franchise. He later explored darker, more unusual, and more independent projects.
His role in Love and Monsters showed a different side of his acting, while All Too Well: The Short Film introduced him to another large audience. More recent projects such as Twinless have also highlighted his range.
Despite this busy career, O’Brien has not used his romantic life as a publicity strategy.
That may explain why interest in Dylan O’Brien girlfriend remains strong. Fans know comparatively little about his private world, so even a simple public appearance can generate significant attention.
What Makes His Relationship History Different?
The biggest difference between O’Brien’s dating history and that of many celebrities is the limited amount of information he personally shares.
His relationship with Robertson was confirmed and lasted several years. Other names have appeared in entertainment coverage, but many were never confirmed by either person.
His connection with Lange stands out because it has continued to appear in public over multiple years. From the 2023 Paris Fashion Week sighting to appearances in 2025 and 2026, there is a consistent public timeline.
At the same time, fans should be careful with claims that go beyond the available evidence. Public photographs can show that two people are spending time together, but they cannot reveal everything about a private relationship.
