The Washington Nationals are owned by the Lerner family, a prominent Washington D.C.-area real estate family whose company, Lerner Enterprises, represents one of the largest private real estate development firms in the mid-Atlantic region. The Lerner family acquired the franchise from Major League Baseball in 2006 for four hundred and fifty million dollars, fulfilling the long-held dream of family patriarch Ted Lerner to restore the national pastime to the nation's capital. Following Ted Lerner's retirement from daily management and his subsequent passing in 2023, his son Mark D. Lerner stepped into the role of managing principal owner, overseeing all operational, sporting, and administrative decisions for the ballclub alongside his family members. Under the Lerner family's stewardship, the Nationals transitioned from a struggling post-relocation club playing in RFK Stadium to opening state-of-the-art Nationals Park, capturing four National League East division titles, and culminating in the historic 2019 World Series championship victory against the Houston Astros.
