Yes. Rooney Mara comes from a wealthy, well-connected American football family.
That answer needs one important qualification. She is a descendant of two NFL team founders. That does not mean she personally owns either team, or that a single family fortune can be stated as one simple number.
The Short Answer
- Her father’s family founded the New York Giants.
- Her mother’s family founded the Pittsburgh Steelers.
- Her father works for the Giants, and her uncle runs the Giants.
- Her uncle on her mother’s side runs the Steelers.
Few actors have a family background quite like that.
Who Are Rooney Mara’s Parents?
Rooney Mara was born Patricia Rooney Mara on April 17, 1985, and raised in Bedford, New York.
- Father: Timothy Christopher Mara, senior vice president of player personnel for the New York Giants.
- Mother: Kathleen McNulty Mara, née Rooney, a part-time real estate agent.
Her father has Irish, German, and French-Canadian ancestry. Her mother is of Irish and Italian descent.
Rooney Mara is the third of four children. Her siblings are:
- Daniel Mara, her older brother
- Kate Mara, her older sister and fellow actor
- Conor Mara, her younger brother
The Two NFL Families Behind Her
This is what makes her background unusual. She is not from one football family. She is from two.
| Side of the family | Founder | Team | Founded |
|---|---|---|---|
| Father’s side | Tim Mara | New York Giants | 1925 |
| Mother’s side | Art Rooney Sr. | Pittsburgh Steelers | 1933 |
Tim Mara paid $500 for the Giants franchise in 1925. Art Rooney Sr. paid a $2,500 franchise fee for the Steelers in 1933.
Rooney Mara is therefore the great-granddaughter of both founders.
The Mara side: New York Giants
Her paternal grandfather was Wellington Mara, the long-time co-owner of the Giants. Her uncle, John Mara, is now president and CEO of the Giants.
The Mara family has owned the Giants since the team was formed in 1925. The ownership structure has changed over time. In 1991, one side of the Mara family sold its half interest to the Tisch family. The Mara family still holds a major stake, but it does not own the whole team outright.
The Rooney side: Pittsburgh Steelers
Her maternal grandfather was Timothy James Rooney, who ran Yonkers Raceway. Her great-uncle, Dan Rooney, was chairman of the Steelers and a former United States ambassador to Ireland.
Her uncle, Art Rooney II, is the owner of the Steelers.
Is Kate Mara from the Same Rich Family?
Yes. Kate Mara has exactly the same parents as Rooney Mara.
Kate Mara is Rooney Mara’s older sister. Any claim that Kate Mara’s family is not rich, while Rooney Mara’s family is, cannot be right. They grew up in the same family, with the same father, mother, grandparents, and great-grandparents.
Kate Mara is known for roles including Zoe Barnes in House of Cards and Sue Storm in Fantastic Four (2015).
How Rich Is the Family, Exactly?
This article does not give a single net-worth total for the Mara or Rooney families.
Team values, family stakes, and other assets are held across many people and companies. Published “family net worth” figures for families like these are often estimates built on team valuations, not confirmed personal wealth. Stating one as fact would mislead readers.
What can be said with confidence is this:
- Both families founded NFL franchises that are now worth billions as businesses.
- The families still hold senior roles and ownership stakes in those teams.
- Rooney Mara grew up in a privileged household connected to that wealth.
That is different from saying she owns a team, or that she inherited a stated sum.
Did Her Background Help Her Acting Career?
Rooney Mara did not start at the top of Hollywood. She started with small roles.
- She attended George Washington University for a year, then transferred to New York University’s Gallatin School of Individualized Study.
- She studied psychology, international social policy, and nonprofits, graduating in 2010.
- She began auditioning at age 19 and appeared in student films.
- Her screen debut was a small role in Urban Legends: Bloody Mary (2005), a film starring her sister Kate.
- She then appeared in the independent drama Tanner Hall (2009).
Her breakthrough came in David Fincher’s films:
- The Social Network (2010), as Erica Albright
- The Girl with the Dragon Tattoo (2011), as Lisbeth Salander
The second role earned her an Academy Award nomination for Best Actress. She later won the Cannes Film Festival Award for Best Actress for Carol (2015) and received an Academy Award nomination for Best Supporting Actress for the same film.
Her family name may have opened doors in general life. Her screen career still had to be built role by role.
Is Rooney Mara Married to Joaquin Phoenix?
Rooney Mara is in a long-term relationship with actor Joaquin Phoenix. The pair became engaged in 2019.
No confirmed wedding announcement has been published, so this article does not describe Phoenix as her husband or give a 2016 marriage date.
They have a son, River, born in 2020, named after Phoenix’s late brother. They welcomed a second child in 2024. The family keeps their children’s private details out of public view, and this article does not add to them.
Frequently Asked Questions
Is Rooney Mara an heiress?
In the loose, everyday sense, yes. She is a descendant of two NFL founders.
In the strict sense, she is not the sole owner or heir of either team. Ownership is shared across family members and, in the Giants’ case, another family.
Does Rooney Mara own the New York Giants?
No. Her family holds a stake in the Giants, and her father and uncle hold senior roles there. She is not listed as the team’s owner.
Does Rooney Mara own the Pittsburgh Steelers?
No. Her mother’s family founded the Steelers, and her uncle Art Rooney II runs the team. That is not the same as Rooney Mara owning it herself.
Are Kate Mara and Rooney Mara sisters?
Yes. Kate Mara is Rooney Mara’s older sister, and both are actors.
Bottom Line
Yes, Rooney Mara is from a rich family. Her great-grandfathers founded the New York Giants and the Pittsburgh Steelers, and her parents and uncles remain closely tied to those teams.
That background is real and well documented. It does not need an invented net-worth total to make the point.
