No, Sidney Crosby does not have any children. Despite being one of the most famous, heavily scrutinized, and globally recognized athletes in Canada and the entire hockey world for the past two decades, Crosby has successfully maintained an extraordinarily private personal life entirely away from the media spotlight. He is known to be in a very long-term, committed relationship with his girlfriend, model Kathy Leutner, and the two have been together for many years, happily sharing their lives between their homes in Pittsburgh and Nova Scotia. However, the couple has not started a family, gotten married, or had any children as of the present day. Crosby strictly keeps his personal and family matters completely separate from his professional hockey career, rarely discussing his private life during public press conferences or media availabilities.
