Born on June 6, 2000, in Switzerland, Moser grew up in Safnern, near Biel, and developed into one of the country’s leading hockey players.
Beyond his NHL achievements, Moser comes from a supportive Swiss family with strong connections to ice hockey. His parents are Thomas Moser and Sandra Moser, and he has two siblings: an older sister named Raina Moser and a younger brother named Sirel Moser.
His mother, a former figure skater, introduced him to skating during childhood. His younger brother also played competitive hockey, while his sister has become involved in a charitable initiative established by the Tampa Bay Lightning defenseman.
Although Moser has spoken openly about his parents and siblings, he maintains a relatively private romantic life. Information about his girlfriend, marital status, and children remains limited.
JJ Moser’s Girlfriend: Is He Dating Anyone?
JJ Moser has not publicly confirmed the identity of a current girlfriend or romantic partner through reliable NHL interviews or established Swiss sports publications.
Although the Swiss defenseman has participated in interviews discussing his life in Tampa, his childhood, and his professional hockey career, he generally avoids revealing details about his romantic relationships.
In December 2024, Swiss newspaper SonntagsBlick published an extensive interview with Moser about his lifestyle in Florida.
During the interview, he discussed spending time with friends, enjoying activities outside hockey, and maintaining connections to his hometown in Switzerland.
However, the article did not identify a girlfriend or romantic partner.
There is also no independently verified public announcement confirming that Moser is married.
Consequently, his current relationship status remains unconfirmed, and there is insufficient reliable information to identify a girlfriend or wife by name.
Does JJ Moser Have Children?
There are no verified public reports confirming that JJ Moser has children.
The Tampa Bay Lightning defenseman has not publicly identified any sons or daughters through official NHL publications or established Swiss sports media.
However, he has spoken about the possibility of becoming a father in the future.
During his December 2024 interview with SonntagsBlick, Moser explained that he would like to have children someday.
He also discussed the possibility of returning to Switzerland after his professional hockey career because he values the country’s lifestyle and educational system.
His comments suggested that starting a family was among his long-term personal goals.
Nevertheless, the interview did not establish that he already had children, and no reliable subsequent announcement confirming fatherhood has been identified.
Therefore, his parental status remains unconfirmed.

Some training sessions required the family to leave home before six o’clock.

Sandra Moser is JJ Moser’s mother and one of the most influential people in his early sporting development.
She is a former figure skater who later became involved in coaching and youth hockey activities in Switzerland.
According to a December 2024 interview with Blick, Sandra taught all three of her children how to skate.

In June 2026, Moser told Plattform J that he had recently spent three days in Paris with his brother and sister.

On August 9, 2026, SwissHabs reported that Janis had established an organization called Platform Mo to support children and young people in the Biel region.
