The Senior club was founded in 1954. It won its first senior championship in 1955 and it was to prove a watershed in the development of football in the parish and county. Doonbeg has dominated the Clare football scene ever since. In the intervening 45 years, the Doonbeg Magpies have contested 26 finals wining 17. (1955,1961, '67, '68, '69, '72, '73, '74, '82, '83, 1988, 1991, '95, '96, '98, '99, 2001) The club has won 14 leagues, 3 U-21 championships, 3 minor championships and several underage competitions. On two occasions Doonbeg succeeded in recording a 3 in a row double (championship and league) 1967-68-69, and 1972-73-74.
The club's greatest achievement was the winning of the 1998 Munster Club Championship - the first Clare club to capture this title. Padraig Gallagher led the side to defeat Moyle Rovers of Tipperary 0-07 v 0-04.
Another proud day for the club was Clare's 1992 Munster championship victory over Kerry in the Gaelic Grounds. Francis McInerney captained the team and with fellow clubmen, Gerry Killeen (who captained Clare to All-Ireland B victory in 1991), Kieran O'Mahoney, Padraig Conway, Pat Blake and selector, Pat Hanrahan, played a part in this achievement.
In 1970 four Doonbeg players, Michael Haugh, Senan Downes, Paddy O'Grady and Jamesie Lynch, lined out together for Munster in the Railway Cup.
