The club was founded in 1954 and won its first senior championship in 1955. 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 by 0-07 to 0-04. Another notable 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 Doonbeg clubmen, Gerry Killeen, Kieran O'Mahoney, Padraig Conway, Pat Blake and selector, Pat Hanrahan, playing a part in the win.
