Beyond his growing reputation as an NFL defensive lineman, Sebastian Valdez’s family includes his father, Jesus Valdez, and his mother, Nora Valdez. Both parents were identified in an official Montana State University football recruiting announcement published in December 2019.

Here is everything publicly known about Sebastian Valdez’s girlfriend, children, parents, siblings and family background.
Sebastian Valdez’s Girlfriend: Who Is He Dating?
As of now, Sebastian Valdez has not publicly confirmed having a girlfriend. There is no reliable, widely documented information identifying a current romantic partner of the San Francisco 49ers defensive tackle.
Unlike some professional athletes who regularly share details about their relationships through interviews and social media, Valdez has maintained a relatively private personal life.
Most publicly available reporting about him focuses on his football development, college performances and transition to the NFL.
His official biographies from the San Francisco 49ers, Montana State University and the University of Washington do not identify a girlfriend or provide details about his dating history.
Therefore, although fans may be interested in knowing who Sebastian Valdez is dating, his current relationship status remains unconfirmed.
Is Sebastian Valdez Married?
As of now, there is no verified public information confirming that Sebastian Valdez is married.
No reliable wedding announcement or established media report has identified a wife or confirmed an engagement involving the NFL defensive lineman.
Without an official statement or credible reporting, it would be inaccurate to identify anyone as his spouse.
Sebastian Valdez’s Children: Does He Have Kids?
As of now, there are no publicly verified reports confirming that Sebastian Valdez has children.
His official football biographies and established sports media profiles do not identify a son or daughter.
Valdez has primarily received public attention for his athletic achievements rather than his personal or family relationships.
He has not made a widely documented announcement about becoming a father.
However, the absence of public information does not necessarily mean that he has no children. It simply means that details about any children have not been independently verified.
Who Are Sebastian Valdez’s Parents?
Sebastian Valdez’s parents are Jesus Valdez and Nora Valdez.
Their names were confirmed by Montana State University Athletics in an official recruiting announcement published on December 18, 2019.
The announcement introduced Sebastian as a defensive line recruit from Monte Vista High School in Spring Valley, California.
Although both parents are publicly identified, detailed information about their professional careers and personal backgrounds is not widely available.
Sebastian Valdez’s Father: Jesus Valdez
Jesus Valdez is the father of San Francisco 49ers defensive tackle Sebastian Valdez.
His name appears in Montana State University’s official football recruiting records, which identify Jesus and Nora Valdez as Sebastian’s parents.
The university included their names when announcing Sebastian’s recruitment to its football program in December 2019.
At the time, Sebastian was an emerging defensive line prospect who had already demonstrated significant potential during his high school career.
Despite his son’s increasing visibility in professional football, Jesus Valdez has remained largely outside the public spotlight.
His occupation, educational background and other personal details have not been extensively documented in reliable sports reporting.
As a result, further claims about his professional life or activities cannot be independently confirmed.
Sebastian Valdez’s Mother: Nora Valdez
Nora Valdez is the mother of Sebastian Valdez.
Like his father, she is identified by name in the official Montana State University recruiting announcement from December 2019.
The document provides confirmation of her identity but does not include detailed biographical information about her career or personal life.
Although Sebastian has discussed his California family connections in interviews about his football career, he has not publicly shared extensive details specifically about his mother.
There is no sufficiently reliable public information establishing Nora’s occupation, age or other personal background details.
Consequently, her life outside her son’s athletic career remains largely private.
Sebastian Valdez’s Siblings: Does He Have Brothers or Sisters?
As of now, there is no reliable public information confirming the names or number of Sebastian Valdez’s siblings.
His official biographies from Montana State University, the University of Washington and the San Francisco 49ers do not publicly identify any brothers or sisters.
Although he has referred to his family in interviews, the available reporting does not establish whether he grew up with siblings.
Does Sebastian Valdez Have a Brother?
No brother of Sebastian Valdez has been publicly identified through the established football biographies and reporting reviewed for this article.
That does not establish that he is an only child. It simply means that details about any brothers remain unverified.
Does Sebastian Valdez Have a Sister?
Similarly, there are no verified public reports identifying a sister of the San Francisco 49ers defensive lineman.
Until reliable information becomes available, claims about his sisters or extended family should be treated as unconfirmed.

How His California Family Connections Influenced His College Decision
Family connections became an important consideration when Sebastian Valdez decided to transfer from Montana State to the University of Washington.
In an April 2024 interview reported by On Montlake, Valdez explained that he wanted to remain on the West Coast partly because his family lived in California.
Washington therefore appealed to him for both football and geographic reasons.

His decision ultimately allowed him to compete at a higher level of college football while remaining in the western United States.

Valdez joined the Washington Huskies for the 2024 season and started all 13 games.
