The club was founded as Ballybay GFC in 1906.
The club is named after the brothers Patrick Pearse and Willie Pearse, executed after the 1916 Easter Rising. Their grounds, Pearse Park, opened in April 1951, the 35th anniversary of the Rising, and were commonly used for inter-county fixtures. A "golden age" followed, Ballybay winning six Monaghan Senior Football Championships in the years 1954-1969.
Ballybay have only won two county titles in recent decades, in 1987 and 2012.
