Rooney Mara: Actress, Activist, and NFL Royalty — Career, Family, and Net Worth

Rooney Mara isn’t your typical Hollywood actress. She’s the granddaughter of two NFL dynasty founders, an Oscar-nominated performer who’s built her reputation on fearless roles, a committed vegan activist, and one half of one of the industry’s most private couples. Despite a family name that echoes across American football stadiums, Mara has carved out something entirely her own in film — and she’s done it on her own terms.

Early Life and NFL Royalty

Born Patricia Rooney Mara on April 17, 1985, in Bedford, New York, Rooney grew up surrounded by one of the most storied family legacies in American sports. Her family connections to the NFL aren’t casual — they’re foundational.

On her father’s side, the Mara family founded the New York Giants. Her father, Timothy Christopher Mara, served as an NFL scout and vice president of player evaluation for the Giants. The family’s football roots stretch back to her great-grandfather, Tim Mara, who purchased the franchise in 1925.

On her mother’s side, the ties are equally deep. Her mother, Kathleen McNulty Rooney, comes from the Rooney family that founded the Pittsburgh Steelers. Her maternal grandfather was Art Rooney Sr., one of the most respected figures in NFL history. Other relatives include Timothy James Rooney, owner of Yonkers Raceway, and her uncle Daniel Mara.

Growing up, football was simply the family business. But Rooney and her older sister Kate Mara both chose a different path — acting.

Education

Mara attended Fox Lane High School in Bedford before enrolling in a gap-year program called the Traveling School, which took her through Ecuador, Peru, and Bolivia. The experience broadened her perspective considerably.

She began her college education at George Washington University before transferring to New York University’s Gallatin School of Individualized Study, where she focused on psychology. The program’s flexible structure let her build a curriculum around her growing interest in performance and human behavior — a combination that would later inform her acting choices.

Film Career

Early Roles and Breakthrough

Mara’s first notable screen appearance came in the 2010 remake of A Nightmare on Elm Street, but it was David Fincher’s The Social Network that same year that put her on the map. Her brief but memorable turn as Erica Albright — the sharp-tongued catalyst for the entire Facebook origin story — showed audiences she could command a scene with very little screen time.

Fincher was so impressed that he cast her in his next film, and the result changed her career forever.

The Girl with the Dragon Tattoo

For the 2011 adaptation of Stieg Larsson’s bestseller, Mara underwent a dramatic physical transformation to play Lisbeth Salander — bleached eyebrows, piercings, a severe haircut, and a performance that was raw and unflinching. The role earned her a Best Actress nomination at the Academy Awards and signaled to Hollywood that she wasn’t interested in playing it safe.

Carol and Continued Success

In 2015, Mara starred alongside Cate Blanchett in Todd Haynes’ Carol, playing Therese Belivet, a young shop clerk drawn into a forbidden love affair in 1950s New York. The performance earned her a second Oscar nomination (Best Supporting Actress), a Best Actress award at the Cannes Film Festival, and nominations for both the BAFTA and Golden Globe.

Other standout films in her career include Her (2013, directed by Spike Jonze), A Ghost Story (2017), Mary Magdalene (2018), Nightmare Alley (2021), Women Talking (2022), and Don’t Worry Darling (2022). She’s also set to portray Audrey Hepburn in an upcoming biopic directed by Luca Guadagnino — a role that’s generated serious anticipation.

Her Sister Kate Mara

Rooney isn’t the only Mara sister making waves in Hollywood. Kate Mara, her older sister, is an accomplished actress in her own right, known for roles in House of Cards, The Martian, and Pose. The sisters share more than a last name — both are vocal animal rights advocates and vegans.

Despite working in the same industry, the two have largely pursued different types of roles. Kate has leaned more toward television, while Rooney has focused almost exclusively on film. They’ve spoken in interviews about supporting each other’s work while maintaining their own distinct identities as performers.

Relationship with Joaquin Phoenix

Mara and actor Joaquin Phoenix first met on the set of Her in 2012, though they didn’t begin dating until they reunited while filming Mary Magdalene in 2016. They’re one of Hollywood’s most private couples and rarely discuss their personal life publicly.

In September 2020, they welcomed a son named River — a tribute to Joaquin’s late brother, River Phoenix, who passed away in 1993. The couple shares a home in the Hollywood Hills and has been spotted at various animal rights events and red carpets together, though they keep public appearances to a minimum.

They got engaged in 2019, and both have spoken about how their shared values — particularly around veganism and activism — form the foundation of their relationship.

Activism and Veganism

Mara’s activism isn’t a side interest — it’s central to who she is. She’s been a dedicated vegan for over a decade and has used her platform to advocate for animal welfare in ways that go well beyond social media posts.

She co-founded Hiraeth Collective, a plant-based luxury fashion label that produces clothing and accessories without using any animal products. The brand reflects her belief that ethical fashion doesn’t have to sacrifice style.

Mara has also worked with Animal Equality, participating in undercover investigations of factory farms. Her involvement in the documentary With My Own Eyes exposed conditions in Britain’s industrial farming operations and drew significant media attention.

Beyond animal rights, she co-founded the Uweza Foundation, which supports education and arts programs for young people in Kibera, Kenya — one of Africa’s largest informal settlements. Her philanthropic work in Kenya has been a long-term commitment, not a one-off gesture.

Rooney Mara’s Net Worth

As of 2026, Rooney Mara’s net worth is estimated at approximately $16 million. Her wealth comes primarily from her film career, which spans over 15 years of critically acclaimed work. Leading roles in major productions like The Girl with the Dragon Tattoo, Carol, and Nightmare Alley have contributed significantly to her earnings.

Her income also benefits from her fashion venture, Hiraeth Collective, and various brand partnerships over the years. Given her upcoming role as Audrey Hepburn in the Guadagnino biopic, her net worth is likely to continue growing.
