Doon GAA is the parent Club of the parish of Lemonaghan/Ballinahown and is one of the oldest in West Offaly.
The club contested it's first Junior Championship final on 20th June 1920. This being the final of the 1919 championships. This game was lost to Clara on a score line of 1-4 to 0-0.
The year 1944 is probably the most significant in the club history, as it heralded the beginning of a golden era in the fortunes of the club. It was their first success in County Champion Football, Doon defeated a well fancied St. Mary's Junior team o a score of 2-7 to 0-2.
In the final of 1945 our minors lost narrowly to Tullamore. The following year the first success of minor level was achieved by defeating the same opposition in the final.
The next success was the Intermediate Championship of 1949 which was played on a league basis. The defeat of Ballycomber was the clinching game of the year. In the 1950's Senior Championship Doon lost to St Mary's by a late goal.
In the early 1950's the flood gates of emigration re-opened. After the Second World War most of the young players of the area were more likely to be found in the playing fields of New York or London than in Doon or Tullamore. As a result the Doon club failed to affiliate in 1952.
The club again affiliated in 1953 and despite a small playing panel that included several veterans they contested the 1954 junior final only to loose to Clara, in 1957 some players from Shannonbridge Parish, which at the time had no affiliated club of its own, assisted Doon to the 1958 Junior Final, only to loose at the hands of Gracefield. 1961 again unfortunately saw Doon unable to a field a team. It was not until 1964 that the Club affiliated to the County Board.
From 1965 to 1973 there existed an arrangement whereby Shannonbridge players played with Doon, during that period the club made 3 unsucessful appearances in Junior Finals losing to Rahan in 1967, St Bridgets in 1967 and Durrow in 1969. They eventually won the Junior Championship in 1970 at the expense of Ballyfore on a score line of 3-12 to 2-3.
The 1980's heralded the rival of a very talented contingent of youthful players and those were to form the nucleus of a team that won the Junior Championship of 1987, Intermediates in 1988 and the Senior B in 1990.
