MASN, or the Mid-Atlantic Sports Network, is a regional sports network jointly owned by the Baltimore Orioles (77% ownership) and the Washington Nationals (23% ownership). It broadcasts sports events primarily in the Washington, D.C., and Baltimore metropolitan areas. MASN offers live telecasts of all Orioles and Nationals games not covered by national broadcasts, along with pre-game and post-game shows. The network also airs collegiate sports, including men’s and women’s basketball, football, and other NCAA Division I events.
As of March 3, 2025, the Orioles and Nationals resolved their long-standing dispute over television rights fees. Under the new agreement, MASN will continue to broadcast Nationals games through the 2025 season. Starting in 2026, the Nationals will have the freedom to negotiate their television rights independently.
