John K. Mara is in his 36th season with the Giants. The franchise's President and Chief Executive Officer, he assumed the team presidency upon the passing of his father, Wellington Mara, in 2005. Mara joined the Giants in 1991 as General Counsel and later added the title of Executive Vice President and Chief Operating Officer.
Mara, one of the NFL's most prominent and respected owners, is the chairman of the league's Management Council Executive Committee, and he played an important role in negotiating the 2011 and 2020 collective bargaining agreements with the NFL Players Association. He also serves on various NFL committees, including the Competition Committee—where he has helped shape league rules and policies for more than 25 years—as well as the Health and Safety, Compensation, Workplace Diversity, and Legalized Sports Betting committees.
Mara has been affiliated with the Giants his entire life. His grandfather, Tim Mara, founded the New York Giants in 1925, and his father, Wellington Mara, became one of the NFL's most respected and influential executives. Both are members of the Pro Football Hall of Fame.
Since John Mara joined the organization in an official capacity, the Giants have participated in 11 playoffs, won five NFC East titles, and played in three Super Bowls, winning two. Along with Steve Tisch, Jonathan Tisch, and Jets owner Woody Johnson, Mara co-chaired the bid committee that helped secure Super Bowl XLVIII for MetLife Stadium. Played on Feb. 2, 2014, between Seattle and Denver, it became the first Super Bowl held in a cold-weather outdoor venue and was widely regarded as a tremendous success. Mara was also instrumental in helping bring the 2026 FIFA World Cup to MetLife Stadium, which hosted eight matches, including the Final between Argentina and Spain on July 19, 2026.
Born in New York City on Dec. 1, 1954, Mara grew up in Westchester County in White Plains and graduated from Iona Prep High School in New Rochelle. He graduated cum laude from Boston College in 1976 with a B.S. in Marketing before earning his law degree from Fordham University in 1979. He specialized in labor and employment law and litigation at two Manhattan firms prior to joining the Giants.
Mara serves on the Board of Directors of Saint Vincent's Hospital in Harrison, N.Y. and the Newark, N.J. Covenant House Action Research Think Tank (CHART), which was formed to combat human trafficking.
John and his wife, Denise, have five children and 15 grandchildren.
